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. This is a terrible loss for all B5 fans and everyone involved with the show wishes to convey their condolences to the O'Hare family. He was an amazing man.

Michael O'Hare (https://tvtropes.org/pmwiki/pmwiki.php/Creator/MichaelOHare) disappeared from public view (https://tvtropes.org/pmwiki/pmwiki.php/ReclusiveArtist/Actors) after leaving Babylon 5 (https://tvtropes.org/pmwiki/pmwiki.php/Series/BabylonFive) early in its run, which together with the show's crew being notoriously vague about why it happened fueled all kinds of rumors. After his death in 2012, it was finally revealed that he had suffered from (https://www.google.com/search?q=Michael+O%27Hare+schizophrenia&sxsrf=AB5stBgvyJV4X96YxSYZZ-0B0ODIsTiRhA%3A1690021098083&ei=6qy7ZLzaBJGbwbkPne-xiAc&ved=0ahUKEwi899qZi6KAAxWRTTABHZ13DHEQ4dUDCBA&uact=5&oq=Michael+O%27Hare+schizophrenia&gs_lp=Egxnd3Mtd2l6LXNlcnAiHE1pY2hhZWwgTydIYXJlIHNjaGl6b3BocmVuaWFIggdQhgJYqwRwAHgCkAEAmAHLAaABhgOqAQUwLjEuMbgBA8gBAPgBAfgBAsICBBAAGEfCAgcQIxiKBRgnwgIIEC4YigUYkQLCAgUQABiABMICBRAuGIAE4gMEGAAgQYgGAZAGCA&sclient=gws-wiz-serp#ip=1) schizophrenia. Although he sought treatment, the delusions and paranoia caused by the disease made it too difficult for him to work and he eventually spent his final several years hardly ever leaving his house and died after a heart attack in a halfway house for the chronically mentally ill. His condition was made public as per his request after his death, to raise awareness and provide an explanation for fans.

The Curse: This sci fi show ("Babylon 5") seems to have created a curse (https://www.google.com/search?q=Babylon+5+curse&sxsrf=AB5stBj7ohPROiCpSIGHS_syEI0ucS-ceQ%3A1690022186489&ei=KrG7ZJynHaiCkvQPr5qE0AU&ved=0ahUKEwic5Nmgj6KAAxUogYQIHS8NAVoQ4dUDCBA&uact=5&oq=Babylon+5+curse&gs_lp=Egxnd3Mtd2l6LXNlcnAiD0JhYnlsb24gNSBjdXJzZTIIEAAYigUYkQIyBhAAGBYYHjIGEAAYFhgeMggQABiKBRiGAzIIEAAYigUYhgMyCBAAGIoFGIYDSJMOUABYlwxwAXgBkAEBmAHlAqABgAyqAQcwLjMuMy4xuAEDyAEA-AEB-AECqAISwgIHECMY6gIYJ8ICExAuGIoFGMgDGOoCGLQCGEPYAQHCAg0QLhiKBRixAxiDARhDwgIKEAAYigUYsQMYQ8ICCxAuGIMBGLEDGIAEwgIHEC4YigUYQ8ICCBAAGIAEGLEDwgIHEAAYigUYQ8ICHBAuGIoFGLEDGIMBGEMYlwUY3AQY3gQY4ATYAQLCAgQQABgDwgIFEAAYgATCAgUQLhiABMICCBAAGBYYHhgP4gMEGAAgQYgGAboGBggBEAEYCLoGBggCEAEYFA&sclient=gws-wiz-serp). That is what fans of the show believe. It is not necessarily what those closest to the situation believe. There is one offspring of an actor victim of the "curse" who has an entirely different theory. The offspring thinks there is no "curse." The offspring's theory is that the series creator (J. Michael Straczynski) has been systematically killing off a cast member (Richard Biggs/44/aortic dissection) (Stephen Furst/63/diabetes) (Andreas Katsulas/59/lung cancer) (Jerry Doyle/59/natural causes) (Jeff Conaway/60/drug overdose) every few years. He considers the show to have been his life's work, and as such wants to garner attention for it in the hopes of getting a reboot with a brand new, younger cast and updated special effects. You may have noticed how he releases a lengthy, heartfelt statement almost immediately after a cast member passes (and often is the one to break the news in the first place). He wants to appear to be a "patriarch" of the cast members, when it's actually not that at all. They live in a state of fear. Prior to the death of this actress (Mira Furlan/65/West Nile Virus), the offspring thought perhaps he was singling out only male members of the cast. "Babylon 5"/J.
