Michael Douglas got rave reviews and is currently a Best Actor Emmy nominee for his terrific performance as Liberace in the HBO biopic, Behind the Candelabra. Personally, I think if that had been a theatrical release here in America, Michael would've had a strong chance of scoring another Oscar nomination. I thought he was way more believable as Liberace than he was as a Broadway director/choreographer in the 1985 movie version of A Chorus Line. I like Michael a lot, but he was more Wall Street than 42nd Street.
...and he was "a cookie full of arsenic" in Sweet Smell of Success with Burt Lancaster.
