Ed O'Ross was born on 4 July 1946 in Pensacola, Florida in the US. Trekkies will recognise him as the actor who played Gaavrin the Tellarite in Star Trek: Enterprise.
After a brief career as a boxer and later a minor league baseball player, O'Ross made his acting debut in the 1982 film Dear Mr. Wonderful. O'Ross has been a guest on such television shows as Moonlighting, Scarecrow and Mrs. King, Murder, She Wrote, Seinfeld, Frasier (starring Kelsey Grammer), Beyond Belief: Fact or Fiction (hosted by Jonathan Frakes), The Handler, NYPD Blue and Boston Legal (starring Rene Auberjonois and William Shatner).
However, he is perhaps best known for his recurring role as Nikolai on the HBO series Six Feet Under, on which he acted with fellow Star Trek performers such as Ed Begley, Jr., Joanna Cassidy and James Cromwell, among others.
In film, O'Ross had supporting roles in such hits as Lethal Weapon (1987), Stanley Kubrick's Full Metal Jacket (1987), Another 48 Hrs. (1990, with Bernie Casey and Biff Yeager), Dick Tracy (1990, along with many other Trek actors, including Hamilton Camp, Seymour Cassel, Colm Meaney, John Schuck, and Paul Sorvino), and Universal Soldier (1992).
In 1987, he co-starred with Michael Nouri and Larry Cedar in the science fiction film The Hidden and appeared, along with Andrew Robinson, Diane Salinger, and Quark actor Armin Shimerman, in the drama The Verne Miller Story.
In the 1988 action comedy Red Heat, O'Ross played the main villain, a Russian drug dealer being chased by star Arnold Schwarzenegger.
More recent films include Hoodlum (1997) and Mindstorm (2001). His latest film role is Delta Farce (2007).
