Jack Nicholson had the best mix for Joker

Thank you, DoctorThirteen. I like the other actors as Joker too, but Jack Nicholson's portrayal is most comfortable.

Thank you, George. Yes, it is.

Thank you, jacotodd47. I couldn't find a collective choice among any of the actors who played Batman. Adam West's portrayal of Bruce was debonair. He had the kindest and calmest rationality for the character, and managed to bring humor in to the man's high education. Michael Keaton had the best balance for Batman, though. He delivered the intimidation that Adam West lacked without carrying the melancholic weight that Robert Pattinson did, and avoided the nonsense that Val Kilmer brought to the screen. The last actor was much too immature as Batman and Bruce, but that matched the very childish nature of Batman Forever. Regarding Catwoman's physical abilities, I agreed with you, but Julie Newmar was better at showing the villainess' sexual obsession with Batman. I also shared your view about Penguin. Frank Gorshin as Riddler was something that I hated. His air was acutely uncomfortable, and laugh very obnoxious. Paul Dano successfully reached the point of the riddling freak: a deranged yet analytical man with a morbid interest in wild violence and psychological games.

Thank you, HellFire. If you look at the whole character, then yes, he is. However, I'm not saying that the performances of the other actors are inferior. Those just have more specific aspects.
