Ex-Men in Trees star James Tupper has landed a new show — and it's not with Anne Heche this time.

The actor has been cast in NBC's new drama pilot, Mercy, about three nurses and friends at Mercy Hospital, The Hollywood Reporter reports. Tupper will play Dr. Chris Sands, a new M.D. at Mercy who had an affair with one of the nurses when they were stationed in Iraq. (So he's a cross between McDreamy and McArmy?)

Tupper most recently guested on Samantha Who?, but is best known for his role on the short-lived Trees, where he met his girlfriend, Heche. Tupper and Heche, who was cast in HBO's Hung last week, are expecting their first child, a boy, later this year.
