Who doesn't love a great action movie duo? Sure, an action/adventure flick doesn't necessarily need a memorable pairing to work, but having two leads who have undeniable chemistry really helps make a movie stand out as a classic of the genre. Some action movies end up being less about fighting and more about friendship. And we wouldn't have it any other way!
Try and imagine Dom Torretto without Brian O'Conner. Think about Murtaugh without Riggs. Can you even envision Mike Lowrey without Marcus Burnett? The answer is no. So, let's bask in some unadulterated friendship, shall we?
