Ashton Kutcher jobs premiere screening autograph

Last night Ashton Kutcher hit the red carpet to promote the upcoming Steve Jobs biopic, and the 35-year-old star put on his very best grandpa sweater and tweeted, "Getting prepped for the LA Jobs premiere. I just want to say thank you to everyone that helped create this life changing experience."

Ashton and his co-stars happily posed for photos and chatted with reporters, but the previous day he took a mini jab at Apple's other co-founder, Steve Wozniak, who hasn't had the most glowing things to say about the film. “Steve Wozniak is being paid by another company to support their Steve Jobs film," Ashton told the Associated Press. "It’s personal for him, but it’s also business. We have to keep that in mind. He was also extremely unavailable to us when producing this film. He’s a brilliant man and I respect his work, but he wasn’t available to us as a resource, so his account isn’t going to be our account because we don’t know exactly what it was. We did the best job we could. Nobody really knows what happened in the rooms.”

Last week, Kutcher echoed that sentiment during an interview with The Hollywood Reporter and added, “The biggest criticism that I’ve ultimately heard is that he wanted it to be represented -- his contribution to Apple -- fairly. And, in all fairness, the movie’s called Jobs. And it’s about Steve Jobs and the legacy of Steve Jobs, and so I think it focuses more ... on what his contribution to Apple was.”
