Sid Haig (Devil's Rejects) and Caroline Williams (Texas Chainsaw Massacre 2, Sharknado 4) had fun with Dickshark at the Days of the Dead convention in Indianapolis.
A fan came up to Bill Zebub to ask him if he'd seen the picture that was making waves. Bill Zebub does not have a smart phone so he could see nothing of the Internet while representing his movie at his booth. The fan showed Bill Zebub the pic, and Bill Zebub waited for a good time to walk over and to thank the celebrities.
This picture is not a celebrity endorsement of the film. Bill Zebub does not use such marketing. What happened in this picture is two celebrities having fun (It was Caroline's idea - she hadn't met Bill Zebub prior to the photo). The reason why this photo is being posted is because it shows how Dickshark winds up in surprising places. Again, it is not a statement about anyone approving of, loving, or promoting the movie. It's just two people having fun with a DVD.
Yes, there ARE celebrities who love certain BILL ZEBUB movies, but Bill Zebub will never exploit that love. His movies are about personal growth, so it would be against his principles to have you blindly follow someone's tastes other than your own. Even among the many people who adore the movies, no two fans are alike in personality. Those who like sheep are focused on money, whereas Bill Zebub is focused on creativity.
