Jon Culshaw

Jon Culshaw did voice work in Death Comes to Time and The Kingmaker. Culshaw is a member of the Dead Ringers comedy troupe.

Culshaw is renowned for his ability to impersonate the voice of Tom Baker as the Fourth Doctor, a role in which he has made numerous sketch appearances as well as prank telephone calls for Dead Ringers. Among the recipients of Culshaw's prank calls from "the Doctor" were Doctor Who actors Sylvester McCoy, Colin Baker, Peter Davison, and Tom Baker himself. In full makeup as Tom Baker, Culshaw interviewed the real Tom Baker, who had no problem with this imitation at all.

He performed the role of Tom Baker's voicemail in The Five(ish) Doctors Reboot, in which Baker himself did not appear except in archival footage from Shada.
