Supernatural Cast: Where Are They Now?
6. Mark Sheppard - Crowley
Crowley is very easily one of Supernatural's most critically-acclaimed characters. Although this can be put down to the sublime writing provided for him, the vast majority of the character's success can be placed on the grand effort of Mark Sheppard.
First introduced during season five as the son of the aforementioned Rowena MacLeod, Crowley was routinely seen as the prime antagonist of the series, ultimately being the third main character to be killed off after Ruby and Bela Talbot.
Post-Supernatural, Mark hasn't been too busy. He starred in eight episodes of the action-adventure comedy Doom Patrol, in which he portrays Willoughby Kipling, while he also had a recurring role as Richard Johnson on Mania City.
In the 2016 rebooted MacGyver series, Sheppard appeared in one episode as an assassin named Jason Tennant, though he also assumes the identity of a fake Dr Zito, a victim of murder. Intriguingly, in the original MacGyver series, Mark's father, W. Morgan Sheppard, played this role, too.
Away from the screen, the voice of Sheppard can be heard within a DLC pack for Call of Duty: Black Ops Cold War, where the former Crowley voices Roman 'Knight' Grey. He's also currently in the process of filming Walker: Independence, playing an as-of-yet unnamed character.
