ldopa links to a Slate article about Linklater’s Slacker. Best bit:
Teresa Taylor (played the infamous pap-smear-pushing Madonna fan): I played drums for the Butthole Surfers. I had gotten it into my head that I was some huge rock star and so I was like, “Well, I guess I’ll be in your little movie.”
[...]
Taylor: [In that scene] I guess it’s obvious that I’m on drugs, right? I’m pretty skinny. I had snorted some speed [the night before]. When I got to the set, I said, “Well, where’s the beer? I need a beer.” And they were like, “Teresa, it’s 9 in the morning. We’re here filming a movie. You can’t get drunk.” And so I was like, “Oh, so this is going to be that kinda deal.”
LOL!
I suppose I should rent it sometime.
