Much like its R-rated Planes, Trains & Automobiles predecessor that starred Steve Martin and the late John Candy back in 1987, Due Date is also the madcap tale of two guys who wouldn't even be friends, let alone take a cross-country road trip together, if extenuating circumstances weren't involved.

On what should've been just another routine flight from Atlanta to LAX, a high-strung, easily annoyed architect and first-time father-to-be (hence the need to get home—pronto) named Peter (Robert Downey Jr.) unexpectedly runs into his worst nightmare, a schlubby, prancing aspiring actor with a really bad stage name who just won't leave him alone, Ethan Tremblay (Zach Galifianakis).

As you probably suspected, Ethan's poor taste in professional monikers is really the least of his problems. Not only does Ethan insist on treating his froofy French bulldog like a pampered child and maintain that he's 23 years old even though he's probably in his mid to late 30s, but his basic people skills (or lack thereof) are where he's probably the most severely challenged.

In a nutshell: He's got n-o-t-h-i-n-g in that department, even with the best of intentions.

In fact, in probably no more than five minutes flat, Ethan's immature antics get him and Peter flagged for the FAA's no-fly list, and they are now forced to find alternate transportation to the City of Angels.

Looking forward to finally saying adios to Ethan for good, Peter then discovers his wallet is missing while trying to rent a car. So with no driver's license, cash or credit cards and a C-section delivery he doesn't want to miss in 72-ish hours, he swallows his pride and agrees to ride with Ethan. After all, how bad can it be, right?

Cue ensuing road-trip hi-jinks.

Considering that Atlanta is a long, long way from Los Angeles, that's a lot of mile markers to cover in the film's 100-minute running time, and unfortunately, some of Due Date's jokes end up scraping the bottom of the barrel for cheap laughs. Truth be told, if it wasn't for the chemistry and comedic prowess of Downey Jr. and Galifianakis in their respective odd-couple roles, Due Date's not particularly original premise would've probably failed spectacularly.

But Downey Jr. and Galifianakis do make a pretty funny pair who can actually learn a thing or two from each other. While Due Date's big laughs certainly aren't as consistent as comedy-lovers would expect, there are some genuinely gut-busting moments that will make it something of a guilty pleasure for some viewers.

And unlike last year's box office smash The Hangover that put director Todd Phillips back on the map in a big way after 2003's Old School, Due Date doesn't just aim to shock and challenge the boundaries of good taste. In all the road-trip craziness which involves everything from an unexpected run-in with Mexican border officials to a detour for the  medical marijuana Ethan needs for his supposed "glaucoma," there's a surprisingly heartwarming underbelly that revolves around the importance of family—yet another quality this film shares with Planes, Trains & Automobiles.

Even as polar opposite as Peter and Ethan are, they inevitably find common ground in acknowledging the importance of having loving fathers—whether it's the one Ethan is mourning and now carrying around in a coffee can or the one Peter is aspiring to be (his own dad walked out on his family) when his wife Sarah (Michelle Monaghan) gives birth.
