Patrick Wilson (Watchmen) has joined Mandate Pictures' romantic comedy Baster, starring Jennifer Aniston, Jason Bateman and Jeff Goldblum.

According to Variety, Miramax Films has acquired North American rights to the film, which is being directed by Blades of Glory duo Will Speck and Josh Gordon.

Based on a short story by Jeffrey Eugenides, the story revolves around friends Wally (Bateman) and Kassie (Aniston), whose plan to have a baby on her own is complicated when Wally secretly swaps Kassie's chosen sperm donation with his own. Allan Loeb penned the screenplay.

Wilson will play the genetically superior sperm donor that Kassie originally selects. Goldblum will portray Wally's boss.

Baster began lensing on Monday in New York.
