Vince Vaughn, Reese Witherspoon, Robert Duvall, Sissy Spacek, Jon Voight| PG-13


If someone climbs onto a roof in a comedy, it’s a sure bet they’ll tumble off sooner rather than later. That’s exactly what happens to Vaughn’s character when he edges onto his father’s roof to install a TV satellite dish in Four Christmases, a predictable seasonal comedy that half amuses in the moment but leaves no lasting impression. Vaughn and Witherspoon play a couple who must, in a single day, visit with each of their wacky divorced parents (Duvall, Spacek, Voight and Mary Steenburgen). How are Witherspoon and Vaughn as a pair? The difference in their heights greatly exceeds their chemistry.
