Guest star ELIZABETH GILLIES (Dynasty) rules over the comedy. Hosted by comedian Aisha Tyler, WHOSE LINE IS IT ANYWAY? features cast members Ryan Stiles, Wayne Brady and Colin Mochrie, along with guest comedian Charles Esten put their comedic skills to the test through a series of spontaneous improv games that are prompted only by random ideas supplied by the studio audience. The four performers must use the little information they have and their wild imaginations to conjure up hilarious characters, scenes and songs out of thin air. After each round of improvisation, Aisha will dole out points to our four performers and declare a winner at the end of every episode.
