Whose Line Is It Anyway? USA

Aisha Tyler serves as the host of the improvisation programme, guiding the performances each episode. The regular cast includes Wayne Brady, Colin Mochrie and Ryan Stiles, who are accompanied in this instalment by guest performer Greg Proops as part of the line‑up.

The series is an improvisation‑based programme presented by Aisha Tyler, who serves as the on‑screen host. Her role is to guide the spontaneous sketches and keep the pace moving, providing the connective thread that ties each segment together. The core ensemble consists of three long‑standing performers: Wayne Brady, Colin Mochrie and Ryan Stiles. These regulars bring their familiar quick‑wit and collaborative style to every episode, and in this instalment they are joined by guest comedian Greg Proops, who adds his own flavour to the unscripted proceedings. Throughout the show, Tyler introduces the games and sets the parameters for each round, while Brady, Mochrie and Stiles respond with the rapid‑fire improvisation that the format demands. Proops steps in as the featured guest, taking part in the same improvised scenes and interacting with the regular trio under Tyler’s direction. The episode therefore follows the established pattern of the series: a host‑led improvisational format, a trio of regular improvisers, and a rotating guest who joins them for the night’s performance. All participants contribute to the fluid, on‑the‑spot comedy that defines the programme.
