Andreas Katsulas, best know as Babylon 5’s G'Kar, passed away on February 13 of lung cancer at age 59.

Katsulas played the Narn ambassador G'Kar for five years from 1993. He reprised the role in subsequent Babylon 5 telefilms.

He also appeared in Star Trek, playing Romulan Cmdr. Tomalak in Star Trek: The Next Generation. His last appearance in a Trek series was as a Vissian captain on an episode of Enterprise.

Born in St. Louis, Katsulas held a master's degree in theater from Indiana University. After performing in plays in St. Louis, New York and Boston, he went on to film roles in such movies as Michael Cimino's The Sicilian, which brought him to Los Angeles, then in Ridley Scott's Someone to Watch Over Me and Blake Edward's Sunset.

Katsulas moved to Los Angeles permanently in 1986 and found television and film parts in everything from TV's Alien Nation and Max Headroom to the big screen's The Fugitive, in which he played the infamous one-armed man, and Executive Decision opposite Kurt Russell and Steven Seagal.

Katsulas is survived by his second wife, whom he married less than a year ago, and a daughter and a son from his first marriage.
