They made Bradley Cooper look like Tom Green. Paul Thomas Anderson is probably the best director working today, and he really does have some of the best trailers.
You could play "Life on Mars?" over any trailer and automatically bump it up to an 8/10 minimum. It's almost cheating.
Looks incredible. Also I love that Cooper is actually playing Jon Peters... and not someone inspired by Jon Peters (even funnier when you remember Peters produced the 70s A Star is Born remake)
I only watched half the trailer and it rules. Haim is definitely playing somebody older than a highschooler
