"Who is your daddy... And what does he do?" Well, for 533 kids in this movie, the answer is Vince Vaughn.

In this brand new trailer for "Delivery Man" (get it?), Vaughn plays lovable schlub (surprised?) David Wozniak, who presumably is no relation to Steve Wozniak, co-founder of Apple and ex-boyfriend of Kathy Griffin. Vaughn's Woz learns that his anonymous sperm donations back in the day resulted in 533 pregnancies. What's a guy to do when he learns that sorta news? Why, head off on a funny but heartwarming journey where he learns all about fatherhood, of course! Faster than you can say "Big Daddy."

"Delivery Man" also stars Chris Pratt ("Moneyball") and Cobie Smulders ("Marvel's The Avengers"). Writer/director Ken Scott is working with the same premise and lead character as his 2011 film "Starbuck." That one only had 142 kids, but it was made in New Zealand, so since this is America that number was, of course, super-sized.
