Yeah, no arguments on any of those points from me. A massive Cary Grant fan, too. England's Marcello Mastroianni, only better. (I'm only half joking with the Mastroianni comparison.)
Just watched ...
Fear and Loathing in Las Vegas.
I don't think this is a bad film but I do think it pretty much says everything it has to say in about the first 30 minutes and that everything after that just seems like more of the same.
