John Sessions
John Sessions (born John Gibb Marshall on 11 January 1953) is a RADA trained actor, comedian and sometimes panellist on British quiz comedies. He is particularly well known, at least in Britain, as one of the original regular panellists on Who's Line Is It Anyway? and, more recently, as a recurring guest on QI.
As of 2014, he has lent only his voice to Doctor Who. Alongside Colin Baker, he was several characters — notably Mozart — in the Big Finish Doctor Who audio story My Own Private Wolfgang. He later starred opposite Peter Davison in Castle of Fear as Roland of Brittany. In the same play, he played the Fifth Doctor in the piece's play-within-a-play. He was also Tannis in the webcast Death Comes to Time. Soon enough, he was on the show, playing Gus in Mummy on the Orient Express.
