With his trademark slacker yakking, unashamed underdog championing and stream of Star Wars references Kevin Smith has probably amassed enough geek goodwill to last him a lifetime.

But his scattergun 15-year career has also contained some credulity-twanging moments sturdy enough to test even the hardiest Clerks-loving fanboy’s resolve.

His latest movie A Couple Of Dicks is going casting crazy, so we've decided to brave giant poop monsters, donkey shows and stink palm pretzels to guide you through Kev’s greatest hits and occasional misses.

Best & Worst: Speech

The Best: Silent Bob Speaks

Film: Chasing Amy (1997)
 

Why It Rocks: It wasn’t the first or last time monged out mute Silent Bob (Kevin Smith, plus unconvincing wig) would poignantly break his silence in a ViewAskewniverse film.

But the sage-like wisdom in this sombre speech about love and loss is both unexpected and terrific. Plus he handily explains the movie’s head-scratchy title ("So I've spent every day since then chasing Amy... so to speak."). Snooch.

The Worst: Let’s Make A Porno

Film: Erm, Zak And Miri Make A Porno (2008)

Why It Sucks: The eye-rollingly unrealistic central conceit that hard-up buddies Zack and Miri would decide to make a skin flick was probably what ultimately sank Kev’s tepidly received last movie.

Despite game delivery from Seth Rogen (“Porn has gone mainstream now, it’s like Coca-Cola or Pepsi. With dicks in it!”) this speech is the flimsy foundation that eventually brings the whole thing crashing down.
