We previously reported that mega pop star Katy Perry would be doing a 3D feature film that was equal parts concert footage and documentary. Now the first trailer has dropped for the movie, titled Katy Perry: Part of Me 3D. It’s as colorful and as emotive as fans of the superstar and her music would expect it to be, but it also highlights Perry’s work ethic and personal struggles, which I found to be a rather mature and enticing angle. Then she shot whipped cream out of her boobs. But it can’t be all sugar and no substance since Hustle & Flow director Craig Brewer has recently signed on as an executive producer. Katy Perry: Part of Me 3D opens in theaters on July 5th. Hit the jump to check out the trailer and find out how you can be a part of the movie itself.
