Greg Sestero stated that when he was writing the book, Tommy Wiseau said that only two actors could play him in the adaptation: James Franco or Johnny Depp. Wiseau, who claims to have once lived in New Orleans, was a fan of Franco's performance in the film Sonny (2002).
In real life Greg and Tommy did not move to Los Angeles at the same time. Wiseau offered his LA apartment to Greg rent free for several months, while Tommy came and went from San Francisco at random. Once Greg had booked some small gigs Wiseau suddenly moved in full time to the LA apartment, demanded rent from Greg and set up the divider in the living room as seen in this film.
To promote the film the distributor rented the same billboard on Highland Avenue in Los Angeles that Tommy Wiseau rented for five years to promote The Room (2003), mimicking the layout of the original billboard and including a phone number to RSVP to screenings.
Seth Rogen and Jonah Hill were early devoted fans of the film. At one point, Hill saw Tommy Wiseau at a grocery store in Los Angeles and was so starstruck that he secretly took a photo of Wiseau shopping that he immediately sent to Rogen.
In actuality, Greg Sestero was never offered a part on Malcolm in the Middle (2000) by Bryan Cranston. Also, Cranston did not begin directing for the series until 2003, a year after The Room (2003) wrapped filming. Sestero stated in his book that he had a beard while filming The Room (2003) until Tommy Wiseau spontaneously decided he should shave it off for the tuxedo scene, and was hesitant do so because he felt having a beard was his disguise and "a key component of my Room anonymity strategy".
James Franco spoke like Tommy Wiseau throughout each day's filming, and even directed using Wiseau's distinctive voice and syntax, though Jason Mantzoukas said that Franco did not direct in character and only spoke like Wiseau. Seth Rogen admitted he had a hard time being directed by Franco while being interviewed on The Howard Stern Show. Rogen said during the first two days, he had a hard time containing his laughter as Franco was speaking as Tommy Wiseau with his notable European accent. Franco told Rogen he would get used to it, which he eventually did.
In almost every interview for The Disaster Artist, James Franco mentions that Tommy Wiseau approves of "99.9%" of the film. His only objections were the lighting of the first scene, which Franco believes was because Tommy was wearing sunglasses when watching the scene, and also for the poor way James threw the football.
In his book, Greg Sestero stated after his first rehearsal with Tommy Wiseau they played soccer, not football as shown in the film, though Wiseau still shouted "touchdown" after scoring a goal on Sestero.
At a Q&A screening of The Room (2003) (before production of this film began), Greg Sestero expressed interest in playing the actor who was originally cast as Mark, who Wiseau fired and replaced with Sestero himself. However, this element of the true story was left out of the final film.
James Franco recalled driving in Los Angeles after 2003 and seeing the giant billboard for the film that Wiseau rented for five years. Franco said he initially thought it might be for a cult, because of the phone number on the billboard. The phone number would go to Wiseau's apartment and there was a recording promoting the film, or he would sometimes answer and tell the caller when and where it was playing.
Besides an interview for Esquire and a video for Funnyordie.com, brothers James Franco and Dave Franco have never worked together or appeared on-screen together until this film. Dave almost appeared as himself with his brother in This Is the End (2013), but he was later excluded because his character would have had to die and it was considered too sad for the already dark comedy. James was also considered for a role in '21 Jump Street (2012) respectively starring his brother Dave.
James Franco played James Dean in James Dean (2001). Dean was a huge influence on both Tommy Wiseau and Greg Sestero, and a major bonding point for their early friendship as detailed in the book and shown in this movie. Even the infamous "You're tearing me apart!" moment in The Room (2003) was inspired by Rebel Without a Cause (1955). Years later when Franco approached Wiseau to play him, Franco learned that he was already a fan of the 2001 James Dean biopic which gave Wiseau the confidence it was the right choice.
The infamous Chris-R scene is being shown as taking place in an alleyway, while in the final film it takes place on a rooftop. It was reshot because Tommy Wiseau thought it would be "more dramatic" on the roof rather than its initial location in an alley. The reshoot cost $80,000 and took two weeks to shoot.
When James Franco won the Golden Globe for Best Actor for his performance as Tommy Wiseau, he called out his brother Dave Franco and the real Tommy Wiseau to the stage. Franco had to prevent Wiseau from taking the microphone, and related a story of how Wiseau was once stuck in a traffic jam caused by the Golden Globes ceremony, and out of frustration of not being invited to that ceremony, he came up with the idea to make his own movie, which became The Room (2003).
Michael Rousselet, who is credited as "Patient Zero" of The Room's cult phenomenon, snuck onto the set for the final scene and is one of the first audience members to high five James as he runs down the aisle.
Before shooting the sex scene, Tommy mentions Alfred Hitchcock being abusive to his actors on the set of The Birds (1963). Melanie Griffith, who appears in this film, is the daughter of actress Tippi Hedren, who appeared in "The Birds" and Marnie (1964) for Hitchock, and who has described that director's behavior as being very possessive and abusive toward her.
In The Room (2003), the character of Peter, the glasses wearing psychiatrist friend who falls down while playing football, suddenly disappears and a new character named Steven appears in the movie with no introduction and speaking lines that would logically have made sense with Peter. However, The Disaster Artist film makes no mention of this and seemingly implies that Peter (played here by Nathan Fielder) was present for the entire film.
All three stars of podcast 'How Did This Get Made?' (Paul Scheer, June Diane Raphael and Jason Mantzoukas) appear in the film. In a Variety article, it was revealed that the podcast episode featuring The Room (2003) which Greg Sestero appeared on, was a contributing factor not only in the source book being completed but also served as an inspiration for the screenwriters.
During the 2018 Academy Awards season, James Franco was being campaigned for a Best Actor nomination. However, shortly after his Golden Globe win, Franco was accused of sexual harassment by former acting students. These accusations came one week before the Academy announced its nominations, and on the day of, the film only received a Best Adapted Screenplay nomination. Franco's exclusion was considered by some as one of the larger snubs of the year.
In the rehearsal scene of "Waiting For Godot," the director says that it's pronounced "Guh-DOH," not "GOD-oh." However, Samuel Beckett stated that "GOD-oh" is in fact the correct pronunciation, thus the actor was actually correct, though that was in all likelihood not the intent here.
Greg Sestero is 6'2, but Dave Franco is 5'7. Tommy Wiseau is 5'9, and James Franco is 5'11 which puts him somewhat convincingly in the ballpark to play Wiseau. Sestero is 5" taller than Wiseau, but James Franco is 4" taller than his brother, Dave. So while the real Sestero was looking down at the real Wiseau while filming The Room (2003), in the film "The Disaster Artist" Wiseau will be looking down at Sestero from roughly the same height difference.
In the early part of the movie, while Tommy and Greg are still in San Francisco, they proceed to a cafe to perform a bit of a live reading of a play. The cafe location (in real life) is not in S.F., it's in L.A., a place called Astro Family Restaurant, located at the corner of Glendale Blvd. and Fletcher Drive. The same cafe is shown a few minutes later when the guys are seen getting a pizza prior to departing for L.A.
The original studio space where most of the interior scenes of The Room were shot no longer exists. But the filmmakers found a soundstage just one block from the original location where the sets were recreated.
The Room had its original premiere at the Fairfax Laemmle theater, which closed permanently in 2010. Finding a suitable theater to shoot in turned into quite a challenge. Virtually the entire cast were needed for the premiere scene. The only days when everyone was available were the 17th and 18th of December, 2016. That also happened to be the opening weekend of Star Wars: The Force Awakens. Most LA theater owners were understandably hesitant to rent out an auditorium on those dates. The production finally settled on the Crest Theater in Westwood.
In actuality, Greg Sestero had no interest in acting in The Room (2003) and originally only intended to serve as the film's line producer, and Tommy Wiseau had cast a different actor to play Mark. Wiseau spontaneously decided the night before filming began that he wanted Sestero to play the role, and Sestero reluctantly accepted after Wiseau offered him a substantial pay raise and a new car. Rather than telling the original actor that he had been replaced, Wiseau had him come to set and perform his scenes for weeks, but instructed the camera crew not to roll any film.
Over 20 minutes of The Room (2003) was painstakingly recreated for this film, including almost exact body movements and lines spoken at nearly identical timing to the original. The Disaster Artist ends with side-by-side comparisons of these scenes. However, the way in which some lines were poorly dubbed in the original was not recreated.
The scene between Greg Sestero and Tommy Wiseau during the premiere of The Room (2003) was largely an invention of the film, as Sestero's book makes no mention of how the audience received the film during its premiere, only that Wiseau was brought to tears by how happy he was. Robyn Paris stated in an interview with Entertainment Weekly in 2008 that most of the audience was "crying with laughter". Sestero also said in Q&A screenings that people who attended were disappointed but amused while some walked out with negative comments heard by Wiseau and Sestero.
The standing ovation at the premiere was fictionalized but represents the future reception when the film became a cult hit. The real reaction of the first audience was uncomfortable silence and awkward laughter (described by one actress as "like trying not to laugh in church"), and some people simply walked out of the theater. The afterparty was equally awkward as guests tried to avoid even discussing the movie. It was not until then-college student Michael Rousselet saw it alone in an empty theater and realized how unintentionally hilarious it was. He called his friends to come watch the next screening and word of mouth quickly spread.
