First person to correctly identify and explain which film Quentin Tarantino is referencing in this scene from Django Unchained will win a prize*.
*Prize may not be anything great, but will be mailed to you, and getting mail is pretty great, right? Answers can be in the form of a reply to this post, or a message here. Hints can be provided, but awesomeness of prize will diminish with each hint given. If more than one person answers correctly, the eloquence and surety of the response will determine the winner. Contest closes in one week (January 21st, 2013, yo).
STILL A REAL THING!
Hint #1: You don’t need to watch the entire scene. All you need is this single frame.
Hint #2: It’s another Tarantino film.
