"We all laughed when it was announced that he was going to be voicing Mario, but seeing the movie, I absolutely loved it. He gives us a surprisingly good performance, even though he does have an American accent."

"Let’s not forget that everyone doubted his ability to pull off Batman. He was in Mr. Mom and Beetlejuice up until then, but he made that role iconic."

"I thought he was gonna be terrible, but he was so good! He actually kept me into the movie. I thought it was going feel like a long three hours, but with how entertaining the movie was, it didn’t feel that long at all."

"The first time I heard about the casting, I was aghast. The guy from the stage musical The Boy from Oz? Seriously?! He’s way too tall, and he’s a song-and-dance man, not an action hero! But, wow, did he nail that role to the point that I feel sorry for whoever tries to embody it next. They have very big claws to fill."

"I know it was just a small part, but I thought he was very funny and very effective. I haven’t seen him in anything else, so can’t comment on his overall acting talent, but he did a good job."

"I was definitely one of those people who, when Heath Ledger was announced as the Joker, was like, 'The guy from A Knight's Tale and 10 Things I Hate About You? That's never going to work!' Then, when the first stills were released and we saw him in Joker makeup sitting in the jail cell, I thought, 'Wow! He actually looks scary!' When I went to see the film, I was forced to eat my early words because, as we know, he was just magnificent."

"I was a huge fan of the first book and super excited when they announced they were making the film. I didn't know who J. Law was before she was cast as Katniss, and my initial thought was, 'How is this blonde bombshell going to play Katniss?!' And to be honest, she never quite matched the picture I had in my head of Katniss, but I was blown away by her performance all the same."

"When I read The Bridges of Madison County, the last person in the world I would have seen as Robert was Clint Eastwood. In my head, he was Dirty Harry. I was irrationally angry when I read that he was not only going to direct it, but also play the sensitive photographer. I had no problem with Meryl Streep as Francesca (because she can play anything). I decided to go to see the movie despite my anger over the casting. Eastwood was fantastic as Robert. He was so good that now I can't imagine anyone else in that role."
