Blooper

James Franco, who has brown eyes, wore colored contacts to more closely resemble Wiseau; however, in some early scenes such as the cafe, Franco is not wearing colored contacts.

The rooftop view from Tommy's apartment is looking southwest to downtown Los Angeles (indicating a view from Echo Park) when seen at night. Later in the film when Tommy is on his roof during the day, the background is looking southeast over Hollywood (indicating that his apartment is now located near Runyon Canyon).

Between cuts once Tommy and Greg are in front of the screen at the premier, Tommy's sunglasses move from being on his head to on his face.

The "shot" scenes we see during the making of The Room are altered at the film's premiere.

At the end of the film, text states that to this day nobody knows how old Wiseau is, where he is from or how he made so much money. In actuality, his naturalization records can be found online that show he was born in Poland on October 3, 1955 and became a naturalized U.S. citizen in 1984 in San Francisco. According to Sestero, he moved to France before immigrating to the United States and changing his name to Thomas Pierre Wiseau (likely from Tomasz Piotr Wieczorkiewicz or Wieczór). Furthermore, a documentary filmmaker discovered he was born in Poznan, Poland. However, it remains a mystery as Wiseau will not confirm these details, and how he became so wealthy is still not known.

The infamous rooftop scene actually took 32 takes to get right; not a deliberate 67 takes in Franco's version.

During the film's premiere, scenes from The Room are shown out of order. Specifically, the "You are tearing me apart, Lisa!" scene is shown before the rooftop "I did not" scene, when in actuality it is the other way around.

In the movie, Sandy shows up at the premiere. In real life, Sandy did not come to the premiere as Tommy had not invited him due to incidents on set; to boot, actor Kyle Vogt didn't even come to the premiere for similar reasons.

The audience did not react in disgust to seeing Wiseau's buttocks during his sex scene. The final cut on the film did not include his nudity despite his insistence because of the disgust shown by others on the set when it was filmed.

The scene in which a star-struck Tommy approaches Judd Apatow in a restaurant takes place in 2002, when it is highly unlikely that Tommy would have recognized him. Apatow had produced the shows Freaks & Geeks (2000) and Undeclared (2001), but did not achieve celebrity status until he directed The 40 Year-Old Virgin (2005) and Knocked Up (2007). However, as Apatow is never identified by name, it could be argued he's playing a fictional producer and not himself, especially as he's much nastier than the real Apatow.

Early in the movie-which is set in late 1998/early 1999-Greg and Amber are watching Gilmore Girls, but Gilmore Girls didn't debut until October 2000.

The LCD camera-top monitors used on the production cameras during the filming scenes did not exist in 2002 or 2003.

Post-2003 cars sporadically drive in the background.

Ready to Rumble poster visible in a 1998 scene. This film came out in 2000; even in a studio, a poster of it wouldn't exist at this time.

The entire film takes place in the late 90s/early 2000s, but a Jack in the Box restaurant can be scene with the modern logo/signage, which was introduced in 2009.

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.

Early in the movie, when Tommy and Greg are in the car together laughing, Tommy calls him Dave. This is the name of the actor, not the character.

Greg Sestero's real mother is French, not American, as portrayed in the film.
