This bromance offers steady giggles, thanks to the odd-couple hilarity of Robert Downey Jr. as an uptight exec and Zach Galifianakis as the wacky actor driving him cross-country. Be warned: Mean-spirited gags dominate, as when the two mistakenly drink Galifianakis' dad's ashes after brewing them as coffee. (Warner Home Video, $29)
