Mark plays the romantic lead in A Snowbound Christmas (2026) as a ranch owner and single father who falls in love with a big city lawyer who gets stranded at his ranch during a blizzard. He has made numerous appearances on the small screen. Mark guest stars in Ballard (2025) as a disgruntled father in a standoff with Maggie Q. He had a recurring role alongside Tobias Menzies and Anthony Boyle in the historical drama, Manhunt (2024), playing Boston Corbett, the man who hunted down and killed John Wilkes Booth.

Percentiles are each film's standing among all films on MovieCove; the typical film is the median, so one outlier cannot drag it. Percentiles and reviewer scores count the films IMDb credits them on, for now; the Midcredits score bands, the shape of the crowd and the two cards count their MovieCove titles, shows included (a show ranked among shows), appearances as themselves left out. A descriptor is the shape of a title's IMDb rating distribution against the catalog; "most divisive" needs a spread wider than half of all titles, and a card names only a principal credit: a craft role, and on a show a crew role or a run of episodes, never a courtesy credit or a one-off guest spot.
