"It's really rare to see such a close knit group as I saw on this film," reflected Jonathan Sehring, the president of IFC entertainment, at last night's New York premiere of On the Road. The cast indeed demonstrated a close rapport—perhaps a result of two weeks of something screenwriter Jose Rivera called "beatnik boot camp," followed by months of shooting. Joked Sam Riley of his co-star Garrett Hedlund, "We managed to pretend to like each other for a whole six months."

The premiere was a relaxed affair. Sky Ferreira, red lipped and pale, sported a baseball jacket and bare legs, in spite of the chilly December evening. Grace Coddington arrived early, wearing her signature head-to-toe black, and surveyed the scene momentarily before quietly slipping into the theater.

Hedlund, Interview's December/January cover subject, towered a head above the crowd, a strong presence in a slim Gucci suit. Kirsten Dunst and Kristin Stewart looked equally lovely in quite opposite ways: Dunst wore a conservative navy Dior ensemble, while Stewart donned a sheer nude beaded Erdem dress. Other notable attendees included writer Derek Blasberg , Emily Meade (one of Interview's 13 faces to watch in 2013), Christopher Abbott, Robert Buckley, Patti Smith, and model Jeisa Chiminazzo.

At the afterparty at the Top of the Standard Hotel, Hedlund and Dunst arrived arm-in-arm. Guests mingled around the bar, sampling lobster rolls and quartered cheeseburgers while swinging to a live jazz band. The crowd, a mix of theater and film people, included director Ryan Fleck and actress Julia Garner, unmissable with her blonde  ringlets. Alexa Chung, wearing a Peter Pan collar, giggled with friends at a table in the corner. The cast huddled around tables near the entrance, while On the Road‘s director Walter Salles and Rivera happily chatted with guests.—Rachel Small
