Hilarious road comedy from "The Hangover" director Todd Phillips stars Robert Downey, Jr. as an expectant father who has five days to make it from Atlanta to Los Angeles to see the birth of his first child. Plenty of time, right? Wrong. Downey's triphas several unexpected setbacks, mostly due to the unbelievably annoying wannabe actor (Zach Galifianakis) he's forced to hitch a cross-country ride with. With Michelle Monaghan, Juliette Lewis, Danny McBride, and Jamie Foxx. 95 min. Widescreen (Enhanced); Soundtracks: English Dolby Digital 5.1, French Dolby Digital 5.1, Spanish Dolby Digital 5.1; Subtitles: English (SDH), French, Spanish; gag reel.
