In real life, celebrities are always smaller than you thought they'd be. Except, probably, for Marcel. No question about it, Marcel's a star. He's got millions of YouTube fans, and his own book deal. And so far, he's coping well -- he's still the same bashful guy he always was. But no one imagines Marcel is larger than he is. Because his fans have all seen him walking around on a cellphone, or heard him say that he sleeps on bread. I guess I should mention that Marcel is a tiny shell. His full name is "Marcel The Shell With Shoes On". And this week, the filmmakers behind Marcel uploaded the second installment.

Dean Fleischer-Camp is the filmmaker behind Marcel -- along with his finacée, Jenny Slate. We reached Mr. Fleischer-Camp in New York City.
