Julliard-trained actor Michael O’Hare who helped launch the Babylon 5 sci-fi TV series by portraying Commander Jeffrey Sinclair in its first season, passed away Friday night from complications of cardiac arrest. He was 60. The show’s creator J Michael Straczynski posted on his Facebook page that O’Hare had been in a coma since suffering a heart attack on September 23rd. In Season 2, O’Hare’s character was replaced for the remainder of the show’s 5-year run by Bruce Boxleitner’s Captain John Sheridan. But O’Hare reprised the role in Seasons 2 and 3 during guest appearances. He appeared on many TV series, including Kate & Allie, The Equalizer, Tales from the Darkside, The Cosby Mysteries, and Law & Order.
