In the summer of 2003, Bob Dylan starred in an extremely bizarre film called 'Masked and Anonymous', set in a post-apocalyptic USA and stuffed with countless cameos.
If you were to describe the plot of 'Old School' out of context to someone who hasn't seen it, it probably wouldn't sound like one of the great comedies. But, with a great cast and strong gags it still remains one of the best of the aughts.
