Ryan's flyin' when Ryan Phillippe makes his Saturday Night Live hosting debut. The actor already has an SNL connection: He stars in the film MacGruber with prime-time players Will Forte and Kristen Wiig. The movie, which is slated to hit theaters on May 21, is based on Forte's riotous SNL sketch about a mullet-coiffed, MacGyveresque action character who always meets his demise thanks to a bomb explosion. As for tonight's big bangs, expect the usual headline-blasting skits and a burst of music when dance-pop songstress Ke$ha hits the stage. — Dean Maurer

Doctor Who
9/8c BBC America
Lamentably, there's no such thing as on-the-job training for Time Lords. One minute, you look like you're pushing 40 and you know your life's purpose, and then there's a bright flash of special effects and you appear to be a decade younger with only the foggiest idea of who — and what — you were just a second ago. Newbie Matt Smith tries to fill David Tennant's running shoes and save the world in less time than it takes to have a pizza delivered. Karen Gillan also debuts as the new companion. — Michael Chant
