Mark Andreas Sheppard (born 30 May 1964) is an English, naturalized American, actor and musician, born in London, England of an Irish-German background. He is often credited as "Mark A. Sheppard". Sheppard is known for his recurring roles as the demon/King of Hell Crowley on Supernatural, lawyer Romo Lampkin on the Battlestar Galactica reboot, Interpol investigator James Sterling on Leverage, and small-time crime lord Badger on Joss Whedon's Firefly.

Personal life

Sheppard is the son of actor W. Morgan Sheppard. He married Jessica on March 6, 2004. Jessica announced that they were divorcing in 2014. They have two children together.

In early December 2014, Sheppard began dating Sarah Louise Fudge, an Australian mining heiress, after meeting her at a convention for his show, Supernatural. They became engaged on August 20, 2015, before marrying in a private ceremony on November 9, 2015, in Denver, Colorado. On September 26, 2015, the couple announced that they were expecting their first child together, a baby girl. Their daughter was born on March 1, 2016.



At 15, he became a professional musician and enjoyed many years as a recording and touring artist with bands including Robyn Hitchcock, the Television Personalities and the Irish group Light a Big Fire. Mark played drums on Light a Big Fire's second album. As a session musician, he recorded albums for many groups throughout Europe, and eventually moved to the United States.


Sheppard was invited to audition for the American production of the play Cock and Bull Story (directed by Midnight Express author Billy Hayes), for which he won numerous awards, including the 1992 L.A. Drama Critics' Circle award and the LA Weekly and Dramalogue awards.


His television work includes the "Fire" episode of The X-Files, a year on the Jerry Bruckheimer action series Soldier of Fortune, guest-starring and recurring roles on The Practice, The Invisible Man, Special Unit 2, JAG, Star Trek: Voyager, The Chronicle, Monk, Las Vegas, CSI: NY, Chuck, CSI: Crime Scene Investigation and White Collar, among others. Mark played a demon named Arnon on an episode titled "Witches in Tights" on the TV series Charmed. He played Badger, a semi-comical cockney-style crime boss in the short-lived Joss Whedon show Firefly and later cast again in another Joss Whedon show, Dollhouse as Paul Ballard's dismissive FBI superior. He has appeared as a villain in season five of the Fox show 24 and as Patricia Arquette's serial-killer nemesis on Medium. He appeared as Romo Lampkin in seasons three and four of Battlestar Galactica, and had a recurring role as Manservant Neville in ABC Family's short-lived cult hit The Middleman. He has been seen as Anthony Anthros on Bionic Woman, as Sterling the nemesis character on Leverage, as the King of Hell Crowley on Supernatural, and as bank robber Tom Prescott on an episode of Burn Notice. He appeared in the pilot episode of the US series White Collar as a villainous master forger and in NBC's Chuck as the Director of the Ring criminal organisation. Most recently, he appeared in the SyFy series Warehouse 13 as Regent Benedict Valda. He appears in the 2011 Doctor Who episodes "The Impossible Astronaut" and "Day of the Moon" playing the character Canton Everett Delaware III. This was the first time Sheppard had appeared in a British TV series. In October 2013, Sheppard returned to White Collar, reprising his 2009 role as master forger Curtis Hagan.


His film credits include the Jim Sheridan film In the Name of the Father, starring opposite Daniel Day-Lewis and Emma Thompson as Guildford Four member Patrick Armstrong; the romantic comedy Lover's Knot; the Russian historical drama Out of the Cold; the thriller Unstoppable; and with Heather Graham and Jeremy Sisto in the dark independent, Broken. He also starred in Megalodon and New Alcatraz.

Mark Sheppard directed his father W. Morgan Sheppard in the film Room 101 and co-stars with him in the psychological thriller Nether World, which the younger Sheppard also co-produced. His father also played the older version of his son's character in the afforementioned Doctor Who and "NCIS" episodes.
