(WXIA) -- Stage and television actor Michael O'Hare, best known for his role as Commander Sinclair on the 90s science fiction series "Babylon 5" died Friday at the age of 60 from complications related to a heart attack last weekend.
News of O'Hare's passing first came from television writer/producer and "Babylon 5" creator J. Michael Straczynski's Facebook page.
"I regret that I must convey the sad news that Michael O'Hare passed away today. He suffered a heart attack on Sunday and was in a coma until his passing this afternoon."
O'Hare was the original lead actor for the syndicated science fiction series during its first season. He left the role prior to the start of the second season to concentrate on his first love, the stage. O'Hare reprised the role later in the series' run to complete Sinclair's storyline.
In addition to his lead role in "Babylon 5," O'Hare appeared in guest roles in a number of television shows including "One Life to Live," "Trapper John, M.D.," "The Equalizer," "Law & Order," "L.A. Law" and "Tales from the Darkside".
On the stage, O'Hare won acclaim in the role of Colonel Jessup in the stage version of "A Few Good Men" before Jack Nicholson made the role familiar to movie audiences in the 1992 motion picture version of the play.
