Season 12

Season 12 of Whose Line Is It Anyway? (2013) is improv comedy you can watch online on iFILM — twenty-two episodes with not a single line written in advance. The audience hands over a prompt; the cast builds the rest in real time.

Aisha Tyler is still running the room alongside the core three of Ryan Stiles, Colin Mochrie and Wayne Brady. The guest list this time runs wide, from Penn & Teller and Keegan-Michael Key to Rachel Bloom, Tiffany Haddish, Alyson Hannigan and singer Jordin Sparks. A handful of episodes are compilation specials, pulling together favorite games, behind-the-scenes bits and footage that never aired. The staple segments return — 90-second alphabet, weird newscasters, scenes from a hat. A theme gets shouted out, the performers scramble, and the dumber the assignment the funnier it lands.

Compared with the previous run, the episode count nearly doubles and the guests carry more weight. There's no plot to follow here; the show is pure reaction and chemistry between the hosts. Stream Whose Line Is It Anyway? Season 12 online on iFILM.
