45 Famous Guest Stars You Forgot Were on 'Law & Order: SVU'

After 20 seasons on air, Law & Order: Special Victims Unit has become known for two things: the surprising plot twists that keep viewers on the edge of their seats, and the epic celebrity cameos. If the plot alone isn't enough to keep you engaged, a guest appearance from an unexpected A-lister will probably rope you in until the episode resolves itself. Believe it or not, many Hollywood stars landed their first roles in this series — so many, that watching re-runs of the popular TV show practically becomes a game of "Where's Waldo?," offering an entertaining glimpse into your favorite actors' early days on the small screen. Even the biggest SVU fans have probably forgotten about a few of these performances.
