Star Wars star Carrie Fisher has said that her manic depression comes from the Irish side of her family and their "commitment to alcoholism".
Speaking on The Saturday Night Show last night (May 31), she told host Brendan O'Connor: "The part of my family that the manic depression comes from is the Irish side who had a commitment to alcoholism that was beautiful.
"My great grand whatever, his name was Burt MacReynolds and he dropped the Mac in the ocean when he came over to America. He was a horse thief."
Fisher (57), who has reunited with original cast members Harrison Ford and Mark Hamill for Star Wars: Episode VII, also said that electric shock treatment has worked in treating her bipolar disorder.
"As far as I can remember, it did work for me but it does shred your memory," she said. "It did work for me, it's like convulsions any more . . . there is part of me that thinks, oh I wish I never started talking about this because now people think I'm nuts but I'm not - I just play that on TV."
Fisher (57) added that she deals with her depression by going on TV and talking about it. "Everyone knows that depression is shite, that's the worst thing going, but mania can be great but the problem I have now is that I fall over things, I'm spilling everything, I'm getting ahead of myself. That sounds like just an expression but you feel you can't catch up with yourself. I'm forever running behind me saying `wait'!"
Asked about reprising her iconic role as Princess Leia, Fisher said: "They're doing it over again so hopefully we'll get it right this time. People always ask me about that metal bikini - now I only wear that when I'm going on trips so I can go through security and the metal makes the machine go off and then they make me strip and bring in Jabba The Hut . . . it's just great.
"I don't have the metal bikini any more. You don't want to see your arms after 40 so . . . "
