Jeff Goldblum set for 'The Baster'

Jeff Goldblum has signed on to star alongside Jennifer Aniston and Jason Bateman in Mandate Pictures' upcoming comedy "The Baster."

The film follows an insecure man (Bateman) who discovers his best friend (Aniston) plans to have an artifical insemination and secretly replaces her donor's semen with his own.

According to the Hollywood Reporter, Goldblum is set to play Bateman's business partner. The trade further describes his character as someone "whose idea of working out is walking slowly on the treadmill while eating a candy bar."

Allan Loeb, whose credits include "21" and "Things We Lost in the Fire," is writing the screenplay. "Blades of Glory" helmers Josh Gordon and Will Speck are set to direct.

Goldblum's recent big-screen credits include "Adam Resurrected" and "Man of the Year."
