was revealed to be a vampire because of Wiseau's fascination with the creatures. Sestero recounts how Wiseau tasked the crew with devising a way for Johnny's Mercedes-Benz to fly across the San Francisco skyline, revealing Johnny's vampiric nature. Filming Principal photography lasted four months. Shooting took place mainly on the Birns & Sawyer soundstage in Los Angeles, with some second unit shooting in San Francisco, California. The many rooftop sequences were shot on the soundstage, and exteriors of San Francisco were greenscreened in. A behind-the-scenes feature shows that some of the roof scenes were shot in August 2002. The film employed over 400 people, and Wiseau is credited as an actor, writer, producer, director, and executive producer. Other executive producer credits include Chloe Lietzke and Drew Caffrey. According to Sestero, Lietzke was Wiseau's ESL tutor and had no involvement in the film, and Caffrey, who had been an entrepreneurial mentor to Wiseau, died in 1999. Wiseau had several problems with his behind-the-camera team, and claims to have replaced the entire crew four times. He also assigned multiple (and often disparate) responsibilities to several crew members, a process Sestero described as "sandwich[ing] two roles into one" that frequently resulted in shooting delays: aside from playing the role of Mark, Sestero worked as the film's line producer, helped with casting, and assisted Wiseau; Schklair also served as a de facto first assistant director, and Birns & Sawyer sales representative Peter Anway acted as another assistant to Wiseau. Wiseau frequently forgot his lines or missed cues, and required numerous retakes and direction from Schklair and a stagehand named Byron; much of his dialogue had to be dubbed in post-production. Soundtrack The score was written by Mladen Milicevic, a music professor at Loyola Marymount University. Milicevic later provided the score for Wiseau's 2004 documentary Homeless in America and Room Full of Spoons, a 2016 documentary on The Room. The soundtrack features four R&B slow jams which play during four of the film's five love scenes; Michelle and Mike's oral sex scene uses only instrumental music. The songs are "I Will" by Jarah Gibson, "Crazy" by Clint Gamboa, "Baby You and Me" by Gamboa with Bell Johnson, and "You're My Rose" by Kitra Williams & Reflection. "You're My Rose" is also reprised during the end credits. The soundtrack was released by Wiseau's TPW Records in 2003. Directorial credit dispute In a 2011 Entertainment Weekly article,
