Ultraviolet was a cult TV series which ran on Channel 4 from September to October 1998.

Written and directed by Joe Ahearne and starring Jack Davenport and Susannah Harker, Ultraviolet charted the exploits of an investigative government unit, armed with the latest weaponry, whose aim was to track down and exterminate Code 5 infected subjects while attempting to work out their agenda.

Stylish, dark and often humourous, Ultraviolet delivered a blend of vampire myth with a modern slant. It is notable that the programme never once mentions the word vampire, instead referring to the antagonists as 'leeches' or a 'code 5 (V) infection'.

Marc played the vampire "Carter" in episode 1 (Habeas Corpus).
