Sal Paradise still loves the mad ones.

Weeks after an international trailer for "On the Road" debuted, IFC Films has released a U.S. teaser, which seems to offer more footage despite being 40 seconds shorter. (Yep, that is "Boardwalk Empire" star Steve Buscemi at one point; yes, you do want to see his scene.)

Directed by Walter Salles and produced by Francis Ford Coppola, "On the Road" is the long-gestating adaptation of Jack Kerouac's seminal novel. Sam Riley stars as Paradise with Garrett Hedlund playing Dean Moriarty. Viggo Mortensen, Kirsten Dunst, Elisabeth Moss and Kristen Stewart all co-star.

As previously reported, the "Twilight" star is naked multiple times in "On the Road," and her uninhibited character engages in a threesome and masturbates two male characters in a car.

"I wanted to do it" Stewart said at Cannes, where "On the Road" debuted. "I love pushing, I love scaring myself."

Burn like a Roman candle and watch the "On the Road" trailer above. The film is set for release on Dec. 21.
