'Due Date' Has Us Thinking About The Best Reasons Ever For A Movie Road Trip

Due Date and Jay and Silent Bob Strike Back and Little Miss Sunshine

"Due Date" is ready to be delivered into theaters this weekend, and this is one birth we don't want to miss. The comedy starring Robert Downey Jr. and Zach Galifianakis got us thinking that road tripping across the country to see your child's birth is a pretty good reason to spend that much time in a car with a strange bearded man. In fact, it's probably one of the best reasons behind a road movie we've seen. So we decided to take a look back to figure out whether our other favorite big-screen road trips were for good reasons or purely for bad behavior.

"Fanboys"

Alright, so traveling across the country and breaking into Skywalker Ranch just so your best friend can see an early cut of "Star Wars: Episode 1 - The Phantom Menace" before he dies of cancer just might beat out rushing to be there for your child's birth. Plus "Fanboys" is just an overall awesome movie, but these guys definitely had some good motivations, which is probably why George Lucas agreed to let their sick friend watch "Phantom Menace" at the end. Two thumbs up!

"Road Trip"

On the other hand, needing to travel across the country because you accidentally sent a tape of yourself having sex with someone else to your current girlfriend might not make you the best guy. Sure, the road trip in "Road Trip" ended up for the best for all parties involved, but still, the reasons behind this little cross country adventure earn it two big thumbs down. (Though the film is pretty funny... and from "Due Date" director Todd Phillips, to boot!)

"Little Miss Sunshine"

When you're driving 800 miles in an old Volkswagen T2 Microbus for the sake of 7-year-old, your justifications for a family road trip can't be too bad. Sure, there were other things at play beyond just getting Olive to the "Little Miss Sunshine" pageant, but with a payoff like seeing her (and her fam) perform a dance routine to "Super Freak," it's totally cool in our books. Two thumbs up.

"Jay and Silent Bob Strike Back"

Hollywood totally had it coming this time. After Jay (Jason Mewes) and Silent Bob (Kevin Smith, who also wrote and directed) found out Miramax decided to make a movie about a comic book based off their likenesses -- and that fans hated it -- they decided to get to Los Angeles and stop that movie from being made. Of course, we got to watch their hilarious exploits in the meantime (hello, Will Ferrell), and we're giving the inspiration for this little trip two enthusiastic thumbs up for being entirely justified.

"The Blues Brothers"

This one's a little tricky. Sure, Jake and Elwood Blues break plenty of rules during their escapade through various states to try to get their rhythm and blues band back together, but it was all for the sake of music, so it can't be all bad, right? Fortunately, the Blues bros get their just desserts at the end of "The Blues Brothers," so we're giving the incentives for this one thumb up and one thumb down (though we'll favor the upward-raised thumb because the movie's so awesome).
