Keira Knightley donned a floor-length Valentino number to premiere Anna Karenina in a blustery Big Apple last night. She was accompanied by her director, Joe Wright, and costars Alicia Vikander and Domhnall Gleeson for the stateside screening of the much-anticipated adaptation of Leo Tolstoy's classic novel. Keira and Joe are close after working together previously on Atonement and Pride and Prejudice. Joe spoke to us about collaborating with Keira for a third time, saying, "We both went on our journeys and I found, when I saw her again, that she had been through some stuff, been through some dark stuff, and she had become even stronger and more powerful."

The NYC screening of the film came for Keira after a UK world premiere and a stop at the Toronto International Film Festival, where she and costar Jude Law hit the red carpet together. At last night's premiere, we caught up with Keira at NYC's Florence Gould Hall. She spoke about her favorite part of shooting the film, what attracted her to the role of Anna, and her exciting upcoming projects. Here's more from Keira:

• On her favorite part of shooting the film: "The whole characterization and trying to figure out what made this person tick, which is always my favorite part of any job, particularly when you’re dealing with someone strange and complex. It's always interesting to try to fit the pieces together."
• What attracted her to the role of Anna: "You would be drawn to play her because she doesn't adapt — you don't totally fall in love with her; you don't totally like her. You also hate her. You also think that sometimes she is ridiculous, but you always kind of understand her. I thought that was an extraordinary group of things, and that it was very true to life. I think most of us are like that most of the time."
• On her "fun" upcoming projects: "I realized at the end of Anna Karenina that I had been doing films for the last five years where I died in pretty much all of them or there was something horrible that happened. I wanted to spend this year doing lighter fare. So, Can a Song Save Your Life? is entirely about friendship, and making an album, and hope. I thought that was quite a nice thing to do at the end of a period of films that had been very dark. Then, I am doing a Hollywood thriller that is not necessarily about hope, but it's a Hollywood thriller — so it's fun!"

Glamour's production of "These Girls" brought many famous faces out to Joe's Pub in NYC last night. Olivia Wilde had boyfriend Jason Sudeikis by her side when she wasn't delivering her monologue on stage, and Amy Poehler met up with friends inside the event. Amy posed with Rashida Jones and Aubrey Plaza after working on They Came Together earlier in the day. Connie Britton, who has the season premiere of Nashville hitting the small screen tomorrow, mingled with Carla Gugino while America Ferrera chatted up Rachel Dratch and Glamour's editor in chief, Cindi Leive. America and Amy kicked off their week at the event following a weekend in upstate New York, where they attended the wedding of Amber Tamblyn and David Cross. Also on hand for the funny evening were Meryl Streep's daughters, Mamie and Grace Gummer, Alexa Chung, Coco Rocha, and Ari Graynor.

Jennifer Garner made a red-carpet appearance with the cast of Butter at the NYC premiere last night. She chose a strapless Gucci gown for the occasion, which came after attending a press conference earlier in the day. Jennifer had Ashley Greene; Olivia Wilde, in Alexander McQueen; and Ty Burrell by her side for both events. Costar Alicia Silverstone missed out on this afternoon's promotional stop but joined them for this evening's screening and later at the afterparty sponsored by Appleton Estate Rum. Jennifer, Alicia, and Olivia mingled with Harvey Weinstein at Double Seven, where they celebrated their premiere.

While Jennifer is working in NYC, her husband, Ben Affleck, is on the West Coast. He attended a charity dinner on Monday night and was spotted grabbing lunch on his motorcycle yesterday.

The Tribeca Film Festival brought out some big names this weekend, starting with Kristen Wiig on Saturday when she celebrated Revenge for Jolly. On Sunday Michelle Williams joined Sarah Silverman and friends at an event for the festival. Michelle also stepped out for boyfriend Jason Segel's Five Year Engagement premiere which kicked off Tribeca, though she was careful not to be photographed at the event. James Franco celebrated his own latest project Francophrenia while Olivia Wilde tended to the Help Wanted shorts program. Among the other celebrity attendees, Abbie Cornish was at The Girl screening.

Emily Blunt and Jason Segel teamed up for the NYC premiere of The Five-Year Engagement at the city's Ziegfeld Theatre last night. The screening served as the official opening of the Tribeca Film Festival — check out all the stars from past Tribeca Film Festivals as we celebrate the start of the annual cinema event! Emily paired a Jason Wu dress with a bright pair of Alice + Olivia pumps. Emily and Jason were joined by their costars Alison Brie and Dakota Johnson.

Other stars turned out for the opening, including Julia Louis-Dreyfus, Leelee Sobieski, a Jason Wu-clad Camilla Belle, Kim Cattrall, and Olivia Wilde in Yigal Azrouël. Festival founder Robert De Niro was on hand with his wife, Grace Hightower. Funny ladies from Parks and Recreation, Aubrey Plaza and Amy Poehler, dressed up to take in Jason's latest hilarious movie, and also to support their small-screen costar Chris Pratt, who's in Five-Year, but couldn't make its debut.

The screening was in honor of Emily and Jason's big-screen romance, but he also had his real-life love there, too. Jason Segel and girlfriend Michelle Williams reportedly got cozy once inside the Ziegfeld and later at the Museum of Modern Art afterparty. Jason even talked about the possibility of marriage on the red carpet, telling reporters, "I hit my 30s and enough became enough. I'm ready to enter phase three. I put the puppets into a closet. I'm getting nice furniture."
