Here’s the teaser trailer for Delivery Man, a new comedy starring Vince Vaughn as a guy who finds out he’s the father of 533 children after a mistake at a fertility clinic 20 years ago. Set for release November 22nd, it’s a remake of the 2011 French-Canadian movie Starbuck. Parks and Recreation’s Chris Pratt is co-starring as Vince Vaughn’s sidekick/lawyer, a role for which he gained 65 pounds, demonstrating a commitment to his craft that should serve as an example to the stars of future sperm donor comedies.
