The trailer for "On the Road," an adaptation of Jack Kerouac's seminal beat generation novel, finally hit the Web and brought the cool of 1960s America with it. We saw Kristen Stewart shake it and roll one up. Garrett Hedlund talks about the dumb stuff that he does and can't explain, and Sam Riley sounds disturbingly like Heath Ledger's Joker.

Here are our five key scenes from the "One the Road" trailer.

KStew Rolls Deep
This is not the Bella Swan you know. This is Marylou, the 16-year-old, reefer-smoking chick that Dean Moriarty (Hedlund) just married. We're not sure if there could have been a more striking image to let us know that Kristen Stewart has left Forks, Washington, far behind her.

A Breezy Drive
Let's take that last part back for one second. If we needed a clearer image that Stewart is removing the mantle of Bella Swan for her future career, we have what looks like a shot of the actress removing something else in the front seat with Garrett Hedlund and Sam Riley: her top. We've seen Stewart with an edge in several of her other films, but for "On the Road," she seems to be bidding "Twilight" adieu in style.

The Freakout
As a key work of the beat generation, what would a film adaptation of "On the Road" be without a good old-fashioned drug freak-out dance? Here we see Hedlund tripping out and getting his freak on. It's rare that we see such a loose Hedlund, and the scene gives a good idea of the kind of shenanigans Dean will be up to.

Cutting A Rug
We saw a snap shot of the so-called "Dirty Dancing" scene in an early still from the film, but actually watching a clip of it in the trailer proved that things are certainly going to get hot.

Every Actor Ever
In case you were wondering, that's Amy Adams laughing on the floor with Elisabeth Moss (who plays Peggy Olson on "Mad Men"). That's also Terrence Howard slaying the sax. And oh, look! It's Viggo Mortensen firing a gun and Kirsten Dunst packing her bags. Watching "On the Road" may turn into a game of "Find the Celebrity Cameo."
