Theis in full swing, with movies like bringing cinephiles in droves to Manhattan's Lincoln Center for the annual event.
One of the other highly anticipated selections this year isthe latest offering from Joel and Ethan Coen. They've each already won four Oscars for their previous works, and it looks like the filmmaking brothers may need to make more room on the trophy mantle.
The folk music-infused drama has received rave reviews. In May, it was honored with the prestigious Grand Prixe jury award at this year's Cannes Film Festival and there's been lots of talk about Oscars already. Actor Oscar Isaac, who has never before lead a major feature, is being touted as a best actor front-runner for his performance as the titular character -- a beleaguered folk musician struggling in 1961 Greenwich Village.
At the film's NYFF red carpet premiere, Mulligan said she was thrilled about all the awards buzz because it brings more viewers to watch the film and to see Isaac's performance in particular.
"Oscar Isaac does such an incredible performance in this," Mulligan told CBSNews.com, "So I want so many people to see it."
The film's soundtrack was co-produced by T-Bone Burnett (a frequent Coen brothers collaborator) and Marcus Mumford, Mulligan's husband and lead singer of the Grammy-winning band Mumford & Sons.
John Goodman, Justin Timberlake and Garrett Hedlund appear in the film in supporting performances.
