Seth Rogen and James Franco in Pineapple ExpressPINEAPPLE EXPRESS

As the happily zonked, pot-dealing Saul in Pineapple Express - written by Superbad screenwriters Seth Rogen (who also stars) and Evan Goldberg - James Franco is wonderfully unpredictable.

Or rather, it would be, if Franco had a better movie in which to display his gifts.
