Trivia: At the beginning, right after Christian sings the 'hills are alive' line, the unconscious Argentinian says something about him having lots of talent, and 'happens' to put his hand on his crotch. Then later in the movie, when Satine is unbuttoning his pants when they are in the elephant for the first time, she calls him a 'big boy' and Toulouse says he has HUGE talent.
Trivia: At the beginning of the film when Colin Hanks' character is trying to set Ben Foster's character up with the unlucky/clumsy blond, he mentions the school name as Rosnell High, which is a thinly-veiled reference to his school in the TV series Roswell High.
