Just in case you didn't find everything you wanted underneath the tree this Christmas — or if you're merely finding it a tad difficult returning to work after the long holiday weekend this Monday morning — James Franco is here with a gift that keeps on giving.Now, you probably already know that James has a younger brother named Dave. Dave Franco is also an actor. He's appeared in movies such as 21 Jump Street, Neighbors, and Now You See Me. James and Dave are currently filming The Disaster Artist, a movie about the making of cult classic The Room, together. James has been posting pictures from behind the scenes on his Instagram account.But did you know that James and Dave actually have another, more elusive brother? Yes, there is a third Franco. In the words of Santa and the M&M's on that wonderful commercial : "He DOES exist." (They DO exist.) Look, here's some proof.
