Laura Dern. If she's good enough for David Lynch she's good enough for me. She's also dated a lot of her co-stars. I also recently watched Wild at Heart and think her and Nicholas Cage are dangerously cute.
Who doesn't love Dennis Hopper. Seriously crazy and has that kind of face you can't look away from.
Madonna and her new Brazilian boyfriend Jesus Luz. She is 50 years old. She doesn't seem to care in that cool way people have. And somehow still has that attitude.. perhaps it has her.
These three are quite respectable even though relatively crazy. (Some more than others) I respect their unabashed living.
