Matthew Gray Gubler Matthew Gray Gubler

Matthew Gray Gubler is usually known as "Gube," but he had a different nickname while directing this week's Criminal Minds.

"Someone started calling me Michael Bay Gubler because there's so much action in this one," he tells "I know so little about action films that it's kind of funny."

Criminal Minds: Top 8 Prentiss moments

"I got extensions this time and I braided them like Milli Vanilli, so I think the fans will be in for a treat. I've got dreadlocks now. No, I'm joking!" he says. "No withdrawal this time. The first one, I didn't know how it would be received and if I would be invited back. The withdrawal was the thought of thinking that would be the last time I'll ever have in my life of having fun directing. But now that I've been blessed enough to come back and do it, I feel a little less withdrawal. This was a sad episode, a very unique episode. I'm very proud of it and I hope the fans will like it."

Criminal Minds airs Wednesdays at 9/8c on CBS.
