19 Awesome Movie Cameos Nobody Saw Coming

2. Mark Hamill - Jay & Sient Bob Strike Back

As Jay and Silent Bob sneak their way onto the Bluntman and Chronic movie set and even end up playing the title characters themselves, they come face-to-face with the movie's supervillain C***knocker, played by none other than Mark Hamill.

Hamill is so unrecognisable in the part that Smith even includes a title card introducing him, before he punches Jay in the nether-regions with his gigantic fist and engages in a totally-not-lightsaber fight with Silent Bob (complete with Hamill dropping the one-liner, "Don't f*** with the Jedi Master, son").

Hamill's cameo comes to an unceremonious end when his giant fist is sliced off by a lightsaber-wielding Jay, at which point Hamill looks directly in the camera and quips, "Not again".

You can argue it's self-indulgent and pandering to Smith's fans, but it sure is a lot of fun.
