oh man i just read something funny!
this was in a 1996 playboy interview
PLAYBOY: Your movie misfits often fight back in funny ways. There's a story that you insisted on filming an alternate line in Benny & Joon at the climax of the love story.
DEPP: That's true. It's right when the music comes up and he looks into her eyes. The line is, "Joon, I love you."
PLAYBOY: And your line was
DEPP: "Joon, I'm a bed wetter." I'm still passionate about that line. I didn't get away with it, but I think it could have gotten a laugh and been touching at the same time. You can't help laughing at the pain of this poor bastard, but he's honest. And more than that... it's easy to say "I love you." The audience expects it. But to say you're a bed wetter, to reveal something like that, is saying I love you. It's saying I really love you, enough to tell you my deep, dark secret.
