My son has also watched it since the inception of the British version and yes Ryan was also involved in that as well I think.I love Whose Line! I used to watch the British version when I was in school. Then it had the US version with Drew Carey as host and the Aisha Tyler took over when they re-revived it again. I believe players like Ryan Styles and Colin Mochire were part of all versions. In fact, I'm pretty sure that Ryan Styles had something to do with getting the US version going because he was a regular on The Drew Carey show before the two of then wound up on Whose Line.
