Elliott's had a heck of a film career that dates back (officially) to 1969. In Tombstone he played the elder Earp brother, Virgil, who, is ultimately handicapped in his right arm after a battle and unable to fight any longer, forcing him to get out of dodge, which is analogous to real-life events.

In recent years, he played Bradley Cooper's elder brother in the Oscar darling A Star Is Born and played Beau Bennett in 80 episodes of The Ranch, Shea Brennan in 10 episodes of 1883, and Perry in the MacGruber series.

His trademark low-register voice is also utilized in animated films like the 2019 Lady and Tramp reboot, Robot Chicken, and Family Guy.
