Will Ferrell and Mark Wahlberg are back together for the new comedy, Daddy’s Home. Ferrell is the stepdad in a family (with mom Linda Cardellini) but he gets major competition when the kids real dad, a spec ops bad ass played by Wahlberg, comes home and is looking to reunite with his kids. The two try to one up each other in increasingly crazy fashion and hilarity ensues. Sean Anders, who directed Horrible Bosses 2, and John Morris, who wrote and produced Horrible Bosses 2, are co-directing and the movie is out on Christmas Day. Check out the trailer below.
