The Guardian's quote from Napier-Bell regarding the Wham! movie seems to come directly off the guy's website, on which he answers a fan's query about whether or not a Wham! movie will ever happen. Napier-Bell notes that people are interested in such a project but that it would all depend on George Michael, who could either disallow rights to the group's music or demand too much control. He states that Michael would likely get to say yes or no to any scripts that come about. I'm sure a greenlight on any film would also depend on whether or not there's any actual demand for a Wham! movie. Are there any fans out there excited about such a thing?
In addition to plans for the Wham! movie, Napier-Bell mentions a few other film projects in the works, including one that's a secret and another that's based on his book You Don't Have to Say You Love Me, which is about the "Swinging Sixties" pop scene in London. Most exciting to me, though, is his claim that there is indeed a screenplay out there for a Bolan biopic. Hopefully that one can really happen. I'll be there opening night wearing a top hat and feather boa.
