Kevin Smith says smoking marijuana makes him a better filmmaker.

The 'Zack and Miri Make a Porno' director-and-writer has smoked cannabis-laced cigarettes up to three times a day since Hollywood funnyman Seth Rogen introduced him to the illegal drug last year and thinks it had improved his scripts.

Jennifer Garner will "kick the a*s" of anyone who makes fun of her husband Ben Affleck. The actress clashed with her "Catch and Release" director Kevin Smith - an old friend of the "Pearl Harbor" star - because she didn't understand he wasn't making serious attacks on the actor.

Smith explained: "Jennifer does not share the same sense of humor as me - she did not like my jokes."
