[Guess Who]

Vin Diesel in Boiler Room

 

[8WON6]

Both from Kill Bill
I'd have to check the Pai Mei runtime.

and also:

 

[MasterOfAllHeSurveyz]

Nothing topping the original triple OG, Raymond "Mouse" Alexander. You a bad mutha when you steal a movie from Zel.

 

[Rev Leon Lonnie Love]

chris brown in Stomp The Yard. Got killed in the first scene and mofos went out in droves so they can watch him.

 

[Spence]

Wayman in Low Down Dirty Shame

 

[Kingshango]

Literally set the stage for the latter half of the movie without saying a word.

 

[BulletProof]

This is the only answer

This is a great answer. Maybe the best.

There's a lot of Marvel post credit scenes and hell even bit roles for huge Hollywood legends that should be mentioned.

That whole scene could have been cut from the movie with nothing lost plotwise, but it is one of my favorite parts in any movie. The whole damn cast was hilarious.
