Filming began on 6 July 1975. The film was primarily shot in New Mexico, with filming locations in Albuquerque, White Sands, Artesia and Fenton Lake. The film's production had been scheduled to last eleven weeks, and throughout that time, the film crew ran into a variety of obstacles: Bowie was sidelined for a few days after drinking bad milk; film cameras jammed up; and for one scene shot in the desert, the movie crew had to contend with a group of Hells Angels who were camping nearby. Bowie, who was using cocaine during the movie's production, was in a fragile state of mind when filming was underway, going so far as to state in 1983 that "I'm so pleased I made that [film], but I didn't really know what was being made at all" and that "My one snapshot memory of that film is not having to act. Just being me was perfectly adequate for the role. I wasn't of this earth at that particular time." He said of his performance: Candy Clark, Bowie's co-star, remembers things differently: "David vowed to Nic, 'No drug use'," says Clark and he was a man of his word, "clear as a bell, focused, friendly and professional and leading the team. You can see it clearly because of (DP) Tony Richmond's brilliant cinematography. Look at David: his skin is luminescent. He's gorgeous, angelic, heavenly. He was absolutely perfect as the man from another planet." She added that Roeg had hired "an entirely British crew with him to New Mexico and I remember David was very happy about that." Roeg also cast Bowie's bodyguard, Tony Mascia, as his character's onscreen chauffeur. Bowie and Roeg had a good relationship on set. Bowie recalled in 1992 that "we got on rather well. I think I was fulfilling what he needed from me for that role. I wasn't disrupting ... I wasn't disrupted. In fact, I was very eager to please. And amazingly enough, I was able to carry out everything I was asked to do. I was quite willing to stay up as long as anybody." Bowie brought a personal library with him; "I took 400 books down to that film shoot. I was dead scared of leaving them in New York because I was knocking around with some pretty dodgy people and I didn't want any of them nicking my books. Too many dealers, running in
