Following his seminal Road Trip, The Hangover director Todd Phillips keeps up the good work with the tale of two oddballs - Robert Downey Jr and Zach Galifianakis - forced to endure each other's company on a crazy, trans-American odyssey. Uptight architect Peter (Downey Jr) is heading home from Atlanta to LA as his wife is expecting their first baby. However, making the same trip is aspiring actor Ethan (Galifianakis), a disaster magnet who gets them thrown off the plane, into a fight with a disabled war veteran and into a tussle with Mexican border guards.
Robert Downey Jr
You've got to warm to a comedy where Robert Downey Jr delivers the line "I have never done drugs in my life" in the opening minutes.
He's smoothball architect Peter Highman, a prickly city slicker with anger management issues who's heading home to LA to witness the birth of his first child.
Arriving at Atlanta airport, his first brush with Ethan Tremblay (Galifianakis) comes when his car door is ripped off by the slacker's loaded buddy while dropping him off for his flight.
A baggage mix-up and a painful run-in with an air marshal results in the pair of them ending up on the "no fly" list and Higham - now without passport, ID or wallet - is forced to accept the offer of a lift from the wired Ethan.
Echoing the classic Planes, Trains and Automobiles, this sees the comedy chemistry between Downey Jr and Galifianakis sparking splendidly to provide a series of surreal setpieces as their road trip lurches from one disaster to another.
Top of the list is a sensationally un-PC run-in with a wheelchair-bound Iraq vet (and Western Union clerk), that leaves the apoplectic Higham battered, bloodied and bruised.
He's not helped by the mentalist Ethan, a self-deluded acting ham and major league dopehead who's transporting his father's ashes to the Grand Canyon in a coffee tin. Oh, and there's Ethan's self-abusing hound Sonny.
Who can resist a film where a chemically-induced mis-reading of a road sign lands the desperate duo in Mexico...rather than a Texaco garage?
