Director: Sean AndersWriters: Sean Anders, John MorrisStars: Will Ferrell, Mark Wahlberg, Mel GibsonSummary:
After finally becoming friends at the end of the first film, Brad Whittaker (Will Ferrell) and Dusty Mayron (Mark Wahlberg) have a co-dad system where their two children, Megan (Scarlett Estevez) and Dylan (Owen Vaccaro), take turns at each father's house. Dusty has also remarried, this time to Karen (Alessandra Ambrosio), a writer, and is stepdad to Adrianna (Didi Costine), Karen's daughter. Brad and his wife, Sara (Linda Cardellini), along with Dusty and Karen, attend a school play for Megan, where she announces to the whole audience that she doesn't like the fact that she has to go back and forth to different houses all the time. Back at the house, after the play, Brad and Dusty decide to do away with having two separate Christmases and instead do one "together Christmas". Dusty, however, finds out his tough fighter pilot/astronaut father Kurt (Mel Gibson) is coming for Christmas..
