While filming Django Unchained, Leo DiCaprio had trouble using so many racial slurs. Sam Jackson told him to man up!

Quention Tarantino's much-hyped film "Django Unchained" takes place in the pre-Civil War south and tells the story of a black slave who gets his wife back from a white plantation owner.

It stars Leonardo DiCaprio, Jamie Foxx, Samuel L. Jackson and a multitude of other famous actors. Fitting of any Tarantino film, the movie is chalk full of vulgar language.

At one point during filming, Leonard DiCaprio, who plays the bigot plantation owner, had a difficult time saying the n-word over and over again. He took a moment to gather himself.

Samuel L. Jackson, who plays the plantation butler, took him aside and, with some rather crude, yet joking language of his own, he explained that this was just a regular Tuesday for them all.

Basically, Jackson told DiCaprio to man up, and they continued with the filming.
