He Literally Scared His Co-Stars
We all know who Michael Caine is, correct? Honestly, every time I hear his name, I think of the Kevin Spacey impression from the Jimmy Fallon’s Tonight Show (if you haven’t seen it, YouTube it right now, seriously). Anyway, when Ledger as the Joker crashes the shindig at Wayne Enterprises, it was the first time Michael Caine had seen Ledger in full make-up. Apparently, he was so frightened, he forgot his lines. Good thing that is all that happened. Don’t give this poor man a heart attack, people.
Maggie Gyllenhaal (Donnie Darko), who portrayed Rachel, was also at said shindig, and also hadn’t seen Ledger in full make-up, prompting her to be so scared she couldn’t actually look at him.
Be honest, if you were at some swanky party and some dude shows up acting, dressing and looking like that, you would be fearful of your life as well.
