Yes, that is film director Kevin Smith without his beard. He doesn't look like the same person. I can safely say that if you planned to buy weed from a guy named Silent Bob and this is the guy that showed up, you'd stuff that $60 back in your pocket and go find someone who looked less like your friend Jeremy's dad.
Of course, as was pointed out by Reddit user evanslist this morning, Smith was asked years ago if he would ever shave his beard. He didn't respond with an answer, instead opting to comment on the questioner's odd references for those who fit in the categories "famous people with beards": Chuck Norris, Chewbacca and Jesus.
Here's the plot synopsis for Yoga Hosers, a film Smith is writing and directing, though he is not yet on the cast list: Two teenage yoga enthusiasts team up with a legendary man-hunter to battle with an ancient evil presence that is threatening their major party plans.
Good call, Kevin. Definitely can't be any beards in a movie about yoga.
