Alan Ruck

In autumn 2016, Ruck began a 10-episode run as Henry Rance, the husband (who has suffered mild brain damage in a vaguely explained accident) of Angela Rance (Geena Davis), better known as the adult Regan MacNeil, the tortured girl (played by Linda Blair) who is possessed by a demon in the 1973 hit film The Exorcist. This Fox TV adaptation is "inspired by" the 1971 William Peter Blatty best-selling novel. In this update, the demon that tortured Regan/Angela as a girl did not die as it did at the end of the feature film, and it now inhabits one of Angela and Henry's daughters. Once again, they must turn to exorcism-practicing priests (Alfonso Herrera and Ben Daniels) for help. Regan/Angela's mother, Chris MacNeil (played by recurring guest star Sharon Gless and Ellen Burstyn in the feature film), is welcomed by the rest of the family but utterly scorned by her own daughter.

In 2012, Ruck was cast in the ABC Family series Bunheads as the husband to Sutton Foster's character, Michelle. In 2013, he appeared in NCIS, guest-starring in the season 11 episode, "Gut Check".

In 2010, Ruck was cast as a lead character in the NBC mystery-drama, Persons Unknown. He also guest-starred on the television show Fringe as a scientist turned criminal, in the NCIS: Los Angeles season two episode "Borderline", and guest-starred as ex-money laundering accountant turned dentist, on an episode of Justified entitled "Long in the Tooth". He also appeared in the Grey's Anatomy season five episode "In The Midnight Hour".

Ruck played the part of a ghost of a family man in the 2008 film Ghost Town starring Ricky Gervais. In 2009, he had a minor role as a married man named Frank in an episode of Cougar Town. In his role, he has problems with his marriage due to a crush he had long ago on Jules, played by Courteney Cox.

Ruck also has a small role in the 2008 M. Night Shyamalan film The Happening. He recently played the role of Dean Bowman in the college fraternity drama Greek. He appeared in a guest role as a manic geologist in an episode of Eureka. Additionally, he plays Mr. Cooverman in the film I Love You, Beth Cooper. In 2009, Ruck filmed the medical drama Extraordinary Measures in Portland, Oregon, with star Harrison Ford.

In the 2007 comedy Kickin' It Old Skool, he appears as Dr. Frye, a possible connection to Cameron Frye; he even mentions still trying to pay off an old Ferrari, a reference to Cameron totaling his dad's Ferrari in Ferris Bueller's Day Off.

Ruck later appeared in the 1989 comedy film Three Fugitives. Following that, he played a significant role as Hendry William French in Young Guns II, the 1990 sequel to Young Guns. He also played Captain John Harriman of the USS Enterprise-B in the 1994 film Star Trek Generations, a role that he has reprised along with Generations co-star Walter Koenig and other Trek alumni in the fan film Of Gods and Men. Alan also played an annoying tourist named Doug Stephens on an ill-fated bus in the blockbuster Speed. Another supporting role was of the eccentric storm chaser Robert 'Rabbit' Nurick in the 1996 disaster film Twister.
