One of Bruce Campbell's lines got the biggest laugh the last time I saw it in the theatre. It was when he looked at Peter's ring with his glasses and said, "Hello!". It was great. Also, for some reason, when Harry tells Bernard to get food for a guest, when Bernard said, "A guest guest?", everyone in the theatre cracked up. Yeah, it was funny, but not that funny. Heh.
Some of my favorite lines are among the common favorites, like:
"So good."
"How does that sound, Tiger?"
"I'm not a bad person. I've just had bad luck."
"A little bump on my head and I'm as free as a bird!"
"I'm the other guy."
Whenever JJJ said "Thank you."
"What the hell!"
"I protected you in high school, but now I'm gonna kick your little ass!"
"Look. Little Goblin Junior. You gonna cry?"
"You are good woman, I am good man...hmm?"
"I like being bad. It makes my happy."
"I hurt her, Aunt May...I don't know what to do."
I love all of the awesome acting from all of the actors in this movie. The performances and deliverance of lines is so awesome. My particular favorite is Franco. He was fine in the first two, but in SM3, he had the most charisma in his role second only to Maguire. I loved all of his amnesia, his realizing, and his creepy bad-guy lines.
