The 2014 Primetime Emmy Awards, airing Aug. 25, will pitt a slew of co-stars against each other: Modern Family's Ty Burrell bumps heads with Jesse Tyler Ferguson for Best Supporting Actor in a Comedy; Downton Abbey's Joanne Froggatt challenges Maggie Smith for Best Supporting Actress in a Drama; and Fargo's Martin Freeman hopes to take down Billy Bob Thornton when it comes to Lead Actor in a Miniseries. And then there's the highest-profile face-off of them all: True Detective's Matthew McConaughey and Woody Harrelson, both competing for the Best Actor in a Drama category.

Here's 15 examples of actors from the same show going head to head for the gold.
