Todd Phillips (Old School, The Hangover) has made a career out of male-bonding road trips fueled by sophomoric indecency, and Due Date is more of the same. It even features Zach Galifianakis as a misguided manchild. Here his Ethan Tremblay is an aspiring actor heading to LA to make it — but as Ethan is boarding the plane, an altercation with Peter Highman (Robert Downey Jr.), a strait-laced architect heading home for the birth of his son (thus the title), lands the two on the "no fly" list. So now they have to share a car to cross the country. Planes, Trains and Automobiles it isn't. Ethan jerks off as a bedtime ritual, and he keeps an annoying French bulldog in a man purse. What's more, the reluctant-buddy arc and the ensuing chaos don't always jell. The film scores best when resident weirdos Heidi (Juliette Lewis as a drug-dealing mom) and Lonnie (Danny McBride as a hick cashier) size up the pair. It ain't old-school Todd Phillips, but it is Todd Phillips.
