According to the industry trade papers, the Matt Allen/Caleb Wilson-scripted film focuses on a couple (Vaughn and Witherspoon, presumably) who attempt to visit all four of their divorced parents' homes over the Christmas season. We'll go out on a limb and guess that hilarity will ensue all over the place.
Vaughn and Witherspoon may also end up producing the film along with Gary Barber, Roger Birnbaum and Jon Glickman of Spyglass Entertainment.
Since winning Academy favor for "Walk the Line," Witherspoon has kept a low profile. She'll star in New Line's thriller "Rendition," which opens on Oct. 12.
Meanwhile, Vaughn is just stuck in the Christmas spirit. In addition to a small role in this fall's "Into the Wild," he toplines the Yule-y comedy "Fred Claus."
