Ryan Stiles
In 1998, Carey successfully got ABC to get an American version of Whose Line? produced. Following the final season of the British version in 1998, the American version premiered, with both Stiles and Carey as executive producers. Stiles and Colin Mochrie were the only two actors to appear in every episode of the US version, though Wayne Brady also became a regular near the beginning of the second season. The series was produced until 2006.
