Vince Vaughn has joined the cast of Etan Cohen's upcoming comedy Daddy's Home.

Will Ferrell stars as a radio executive, who strives to be the world's greatest stepfather. His plans are disrupted when his wife's freeloading ex-husband comes back into the picture and forces him to compete for their kids' affection.

Etan Cohen is directing from a script he co-wrote with Brian Burns, Adam McKay and Chris Henchy. Will Ferrell and Adam McKay are producing alongside Joe Drake, Nathan Kahane, Matt Leonetti, Spencer Wong and Jessica Elbaum.
