Mark Sheppard



Mark Sheppard, a fan favorite across popular science fiction and fantasy TV series: Doctor Who, Supernatural, Firefly, Battlestar Galactica, Warehouse 13, Star Trek: Voyager, The X-Files, Sliders, Chuck, Dollhouse, Charmed, Medium, The Bionic Woman and more.

Best known to Doctor Who fans for his 2011 role as “Canton Delaware III,” a taciturn FBI agent who helps the Doctor repel an alien menace during the historic Apollo 11 moon launch, Sheppard will join Catrin Stewart, who plays Doctor Who’s mystery-solving Victorian heroine “Jenny Flint,” and classic Who composer Dominic Glynn, among other guests.
“It’s a thrill to welcome Mark to Con Kasterborous,” said show organizer Bonnie Auten, who founded the con in 2012. “Fans have been delighting in Mark’s charismatic performances and weird, wonderful characters for decades, from his menacing pyrokinetic killer in an early X-Files to conniving ‘Badger’ in Firefly, from Supernatural’s unforgettable ‘Crowley’ to Doctor Who’s heroic ‘Canton Delaware.’ It’s fair to say that any show is improved the moment Mark enters a scene —
The son of veteran British thespian Morgan Sheppard — who joined him on Doctor Who as an older “Canton Delaware,” reunited with the Doctor long after their encounter in 1969 — Sheppard got his acting start in the 1992-93 series Silk Stalkings and in the Oscar-nominated 1993 film In the Name of the Father. His other movie appearances include Lady in the Box, Evil Eyes, Unstoppable and Mysterious Island — which he also directed — and he held recurring roles on other series including White Collar, Leverage, 24 and Soldier of Fortune, Inc. He starred in an early 1990s production of Billy Hayes’ Cock and Bull Story, for which he received the 1992 L.A. Drama Critics’ Circle Award. He also voiced the protagonist of the 2009 videogame The Conduit, in which he was reunited with his father Morgan Sheppard, who played his mentor.
Before taking up acting, Sheppard was a trained musician who performed and toured with, among others, Robyn Hitchcock and the Television Personalities. As a session artist, he backed records cut by numerous bands across Europe. Since 2011, he’s been “The Voice” for BBC America, the cablenet that imports Doctor Who and other British entertainment stateside.




Dominic Glynn


Prolific British composer Dominic Glynn, who revitalized Doctor Who’s classic theme for “Sixth Doctor” Colin Baker in 1986 and scored episodes of the series until its classic run ended in 1989, will be a headliner at Con Kasterborous 2018. The premiere southern Doctor Who convention is set for June 9-10, 2018, at the Westin in Huntsville, Alabama.

“We are thrilled to welcome Dominic Glynn to Huntsville for our seventh annual con,” said organizer Bonnie Auten, who created the event in 2012. “Dominic has been on our radar for ages, and we’re thrilled the stars have finally aligned to welcome him into the Con K family!”

Glynn was among the rare composers tapped to rearrange the iconic Doctor Who theme created in 1963 by Ron Grainer and Delia Derbyshire. His version, used on TV during Season 23, remains the Sixth Doctor’s signature theme in new audios from Big Finish Productions. Glynn went on to compose incidental music for the Doctor Who TV episodes “The Mysterious Planet,” “The Ultimate Foe,” “Dragonfire,” “The Happiness Patrol” and “Survival.”

A regular writer for Universal Music Publishing Group and other production music libraries, Glynn’s composing credits range from the theme to the hit Dutch TV thriller “Vuurzee” to the interstitial Adult Swim “bumps” on the Cartoon Network’s late-night programming block. His work has appeared in episodes of “The Simpsons,” “American Idol,” “Red Dwarf,” “Dead Like Me” and “Eerie, Indiana,” as well as the film “Holy Man.” He scored the British thriller “Bad Day” in 2007, contributed to the 2011 documentary “You’ve Been Trumped” and its 2014 sequel, and composed the score to the 2014 movie “A Dangerous Game.” He also wrote music for “Blake’s 7” audio plays by B7 Productions, based on the late-70s cult TV series.

A stalwart of the alternative electronica field, Glynn runs the No Bones Records label, recording under the names “Fluid” and “Cybajaz” and with Justin Mackay as “Syzygy.” He is a regular DJ at the Big Chill music festival. He also composed music for the Acclaim Entertainment video games “Forsaken” — performing as The Swarm — and “Re-Volt.”
