Onscreen BFFs: Actor Duos Who Keep Playing Friends

True Detective premieres this weekend on HBO and stars Matthew McConaughey and Woody Harrelson as detective partners, but it's not the first time the two actors have appeared on screen together. They're just one example of repeat collaborators (like actors who keep playing couples and the frequent director/star combos), and we love seeing the kind of platonic chemistry between friends who clearly enjoy each other's company once the cameras have stopped rolling. Check out all the stars who keep popping up as friends on the big screen!
