Despite these techniques, Pennebaker has acknowledged that the resulting film was "very sloppy". According to film critic Phil Hall, it remained in post-production for years "due to Pennebaker's inability to achieve an adequate soundtrack mix". Bowie, having abandoned the Ziggy Stardust character and moved on, was less than responsive to the filmmakers' requests for his post-production input, later saying that Ziggy Stardust "was something that I couldn't look at for years...I was so fed up with ." By the early 1980s, Bowie had overcome his reluctance enough to consider the film a "funny film" due to his Ziggy-era style of dress, and to work with Tony Visconti on remixing the soundtrack, saying "I don't know what I was on when I did it the first time".
