Re: Which actor is most bitter?
As DWF said, there's a big difference between being bitter, and just being an actor who's hoping to keep working for another 20 or 30 years, but is worried that typecasting from a big success might get in the way of that. It's also a pretty common thing for stars to relax about talking about their earlier big success once they hit the age when 'normal people' would be retiring anyway (and they realise that being remembered for anything after that long is still a massive achievement): forget about Who, look at Honor Blackman, Leslie Phillips, and so many more.
It probably helps that this tends to be around the point when youngsters who grew up idolizing them become prominent enough in the business to start offering them work...
How many people really remember Honor Blackman for her role in Doctor Who though? Took me a few minutes to remember she did Terror of The Vervoids.
Now if you mention Pussy Galore but she wouldn't have the role if weren't for Cathy Gale in the Avengers.
Or have I just illustrated your point?
Actually, I was referring to the way during the 70s and 80s Honor Blackman would chill up on chat shows if the host tried to talk about The Avengers and Bond. She started loosing up in the 90s, once into her late 60s. Vervoids is just one role she did during the time when she was trying to shake off the Avengers image.
