Benrubi starred as one of the main characters in ABC's show Men in Trees, playing bartender/millionaire Ben Tomasson. This was a role where he got noticeably more main dialog and depth than with his previous longtime characters on ER and Parker Lewis Can't Lose, which primarily consisted of supporting dialog. Ben Tomasson was described as "the cuddliest TV character since Jorge Garcia's Hurley on Lost" by TV-critic David Bianculli. Other previous work includes playing Mose in the 2003 western Open Range, a role the actor won because he had been cut out of Director Kevin Costner's previous film, The Postman. He frequently voices characters on Adult Swim's stop-motion animation show Robot Chicken, and has also contributed to a second show from Chicken's creators, Titan Maximum.
Following the cancellation of Men In Trees in early 2007, Benrubi returned to the cast of ER in late 2008 for the show's final season.
Benrubi starred in the short lived (April 2010 to June 2010) ABC show, Happy Town where he played the part of Big Dave Duncan. Almost right after the series's cancellation was announced he appeared in a new show Memphis Beat, where he plays the part of police Sgt. Jody "JC" Lightfoot, a desk sergeant that is 1/16 Chickasaw by a distant relative, but chooses to embrace Native American culture all the same.
In May 2011 it was announced that he would star in Glutton, a "3D psychological thriller" directed by David Arquette. Benrubi will play Jethro, a 1,200-pound man, forced to save his sister's life. Jethro's sister is played by Patricia Arquette, while Kacey Barnfield also stars as his blind neighbour and only friend.
