Zach Galifianakis

Zach Galifianakis (Warner Bros.)

After showing gravitas in such recent projects as "Iron Man" and "Sherlock Holmes," Robert Downey Jr. goes for laughs again in this mildly amusing comedy from "The Hangover" director Todd Phillips.

After getting booted off a plane and put on the no-fly list because of a fellow passenger's (fellow "Hangover" alum Zach Galifianakis) antics, Downey's character is so desperate to reunite with his wife (Michelle Monaghan) before she gives birth, he accepts a cross-country ride from the other fellow. As might be expected, it's hardly a smooth trip. Jamie Foxx and Alan Arkin also appear. DVD extras: deleted scenes; outtakes; two "mashups"; digital copy of the movie. *** (R: AS, P) (Also on Blu-ray)
