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.

Mark Sheppard directed his father, actor W. Morgan Sheppard in the film Room 101, and co-starred with him in the psychological thriller Nether World, which the younger Sheppard also co-produced. The elder Sheppard played the older version of his son’s character in the aforementioned Doctor Who and NCIS episodes.
He voiced the role of protagonist Michael Ford in The Conduit, whose mentor, John Adams, was voiced by W. Morgan Sheppard.
Sheppard was cast with his father as the same character on three occasions, each playing the character at different ages:
• Canton Everett Delaware III in the Doctor Who episode “The Impossible Astronaut”;
• War criminal Marcin Jarek a.k.a. “Mr. Pain” in the NCIS episode “Broken Bird”; and
• Captain Nemo in the 2010 film Jules Verne’s Mysterious Island, which Mark also directed.
In the Macgyver reboot episode, “Cigar Cutter”, which first aired 14 April 2017, he plays an assassin who assumes the identity of murder victim “Dr. Zito”, a role his father played in the original series, except “Dr. Zito” was the name of the killer.
