Something I didn't know until recently is that the late Jerry Doyle had a radio show where he briefly talked about his experiences with Michael O'Hare. I've found a podcast site that archives all of the episodes but I don't know which episode it was or how long ago this was recorded. So hopefully the quotes I found are accurate.
My first season of Babylon 5 working with Michael O'Hare, he's a
whack-job a complete lunatic. He flies out from New York, he gets the
gig, we're doing our rehearsels he says to me one day "Uh can you give
me a ride out the the set?" yeah sure! "Wanna stop and have
breakfeast?" yeah good! He gets in the car and he's playing with the
buttons in my car trying to turn the radio off and I'm like what are
you doing? And he goes "I don't want any sound" and I go well why dont
you just ask me to turn it off? And he goes "I dont want to talk
today!" And I say well why do you want to go to breakfeast and he goes
"you talk, I'll listen!" so obviously we hurry through breakfeast, we
go out to the set and I realise I'm dealing with a complete nut-job
After we finished that first Friday night we go to this bar in Santa
Clarita and I'm off in one corner talking to this actress Pat
Tallman..just chatting her up having drinks we just got done shooting.
He comes over and sits between us and I go oh ok...he was number 1 on
the call sheet, he was the lead. He was the guy that got all the media
interviews..because he was the lead on the show, and the face and
voice on Babylon 5. So he's chatting her up and I'm like "Oh..ok..I'll
just talk to the bartender here..." and order 3 more drinks. He turns
around, looks at the 3 drinks and says "What is that?" and I say
"umm...I'm buying a round..", and he says "Dont try to control me!!"
and I went "oh..o...k..." this guy is a complete lunatic!
Now outside of the fact that he sexually harrassed an 18 year old
makeup artist and hair gal because he's talking about how its lonely
to be on the road and well he did certain things at night with her in
mind I thought thats a very nice thing to address to an 18 year old
that was interning on a show, not making any money trying to work her
way up in the union.
He punches a female actress on the set. He comes after me we have the
big meeting. Finally I say to him "Michael is there an Indian behind
every tree?" and he says "maybe..you and I will settle this May 26
after we wrap production" And at the end of all this I went back to
the guys and said you know what? I don't need this crap..I dont need
As schizophrenia runs in my family, I can sympathize with Doyle and anyone else who had to deal with the unpredictability of a mentally ill person. Some people are better equipped to handle it than others but in this case, O'Hare tried and failed to hide it from everyone.
Also, here is a link to SciFi Debris' review of War Without End, wherein he touches on O'Hare's final days with the show.
