When he was interviewed about the film, Rik Mayall said that he considered the film as a 25th Anniversary film, as production on this film commenced about twenty-five years after Rik Mayall and Adrian Edmondson first met each other at university, which led them to becoming real-life best friends, and a comedy duo.
The scene in which Ritchie yanks Eddie's head back with a hook up his nose was shot with the action in reverse, then played backwards in the final cut. To achieve this, Adrian Edmondson learned to phonetically pronounce the phrase "Excuse me one moment" backwards.
In this movie, Vincent Cassel plays a man about to marry "the most famous Italian movie actress in the world". In reality, Cassel is married to Monica Bellucci, arguably the most famous Italian movie actress in the world.
Those paying close attention would have noticed that the neighboring power station is a subtle rude joke. The smoking tower and the two domes below are amusingly (albeit juvenile) shaped to resemble a penis and testicles.
In the making of the film documentary, Adrian Edmondson stated he enjoyed making the film and that would he would like to do another film. Unfortunately a "Guest House Paradiso" sequel never happened. After their final live stage show Bottom Live 2003: Weapons Grade Y-Fronts Tour (2003).

In the original promotional campaign for this film's cinema release, Rik Mayall and Adrian Edmondson explicitly stated that it was "not Bottom" (hence the name differences, and other inconsistencies with the series in the movie) but they also said that they have pretty much always played the same characters for years (The Young Ones (1982), Filthy Rich & Catflap (1987), and Bottom (1991)) and this was just a new set. Perhaps the films not-so-stratospheric box-office success caused the studio to add "The Bottom Movie" on its video release.
Rik Mayall was originally going to co-direct, but he declined, because he was still recovering from his quad bike accident. Rik and Adrian Edmondson wrote the first draft of the script while Rik was in the hospital.
The idea for the film came about, when Rik Mayall and Adrian Edmondson were staying at hotels, when they went on tour across the UK, performing live stage shows of their hit television sitcom Bottom (1991), of which the film is spun-off, and they thought it would be funny if Richie and Eddie ran a hotel.
Rik Mayall and Adrian Edmondson changed the surnames of their characters for the film. Edmondson's character Eddie's surname was changed from Hitler to Ndingombaba and Rik's character Richie's surname was changed from Richards to Twat, which became a recurring gag throughout the film, as Richard claims his surname is pronounced "Thwaite", when it is spelt Twat.
The subplot where the guests eat the radioactive fish, get sick and projectile vomit everywhere, is reference to Bottom Live 3: Hooligan's Island (1997), in which Richie eats a bad fish that causes him to projectile vomit.
When Eddie brings Gino to Gina's hotel room, Eddie asks Gino to mind his language and states that Richie and himself are trying to keep the film PG rated, when Gino calls him a "Dead Motherf*****". That was a joke that was written to poke fun at the film's 15 rating in the United Kingdom. The film is given the 15 certificate for it's comic violence, profanity, sexual content, and gross humor. The Bottom (1991) television show, from which the film is spun-off, was given a 15 certificate when it was released on VHS and DVD.
For the sequence, in which Richie accidentally gets Eddie's fishing hook caught in Mr. Nice's nipple ring, trying to recover the security videotape. Simon Pegg wore a prosthetic torso and nipple. This was rigged up to wires, to lift him up off the bed, which were pulled by the special effects crew. To give the illusion that Richie and Eddie are lifting Mr. Nice off the bed into the air with the fish hook caught in his nipple ring.
Rik Mayall stated in the behind the scenes documentary, that in the backstory of the little crawlways hidden between the walls of the hotel, were designed by Richie's Great Uncle Gervais. Richie could crawl through, open little doorways, and have a peep at the guests in the hotel when they were getting sexy.
For the sequence which Richie is swinging Eddie through the air with the meathooks in his nose, and throws Eddie through the kitchen window, was achieved with Adrian Edmondson lying on top of a rotating board and dummy arms of Rik Mayall with the meathooks was used, which Edmondson put in his nostrils during filming, to give the illusion that Mayall is swinging Edmondson through the air.
When they filmed the scene which Eddie asks Richie to remove his hand from his groin, when Mr. Nice takes the security videotape. Adrian Edmondson made Rik Mayall crack up laughing when he broke character and whispers to Rik Mayall "I like it. Put it back on."

When the scene in which Mrs. Nice and the kids catch Richie and Eddie getting dressed outside Gina Carbonara's room. In one take, Adrian Edmondson accidentally knocked Rik Mayall on the side of the head.
The gag which the sound of bells donging are heard when Eddie wriggles his hips in the Eddie the Bellboy sequence was reused from Bottom Live 3: Hooligan's Island (1997) which the sound of bells donging is heard when Richie kicks Eddie in the groin.
