Robert Downey Jr (Ironman) and Zach Galifianakis (from the hangover) star is this must-see comedy about an expectant father trying to get to the birth of his first child on time. A very similar concept to the 1987 hit 'Planes trains and automobiles' with Steve Martin and the late John Candy.
After being put on the no fly list and having his wallet and person effects stolen Peter Highman, an architect with a very short temper, is forced to accept the offer of a ride with the aspiring actor Ethan Tremblay.
From the very beginning to the very end you'll be doubled over laughing, clutching the armrest in anticipation (or horror) and you'll leave grinning and telling all your friends to go see it. Notable moments of hilarity (without spoiling it for you): The car accident, the coffee tin, when Peter punches a kid, the possible black father of his child, the escape from Mexico, and so so many others.
Zach is infuriatingly annoying but loyal and Robert is in a bug-eyed rage half the time.
Worth spending your money on, take a friend with a sense of humour and enjoy!
