Did you think one of the lives was his actual life?

Wrong question. The real question is: Does he have one? And what does that mean: Living compared to playing a role...

If so, I'd say it was the one with his "daughter", but in this bizarre movie, who knows?

Schrodinger's cat walks into a bar, or doesn't.

Not the ones he played. The relationship he had with the actress that killed herself seemed real... after all he was supposed to have one more appointment, and that happened after this one.

I wonder if she really died. I mean, that would be a bit extreme (and they'd run out of actors...), and he died a few times before during the day, but those things were easier to fake. A few squibs, a bit of fake blood... but she and that other guy had to get down there pretty fast.
