Greta Gerwig stood out on the red carpet at the premiere of 'Arthur' in New York last night (06.03.11).

The stunning actress - who plays Naomi in the movie - looked radiant in a black and white ensemble as she attended the event with her co-stars Russell Brand, Helen Mirren and Jennifer Garner.

An eyewitness told On Location Vacations that the 27-year-old blonde was happy to talk to fans and sign autographs before going into the city's Zeigfeld Theatre to watch the film.

They said: "Jennifer Garner only had time to sign for half the line of fans and as she was entering the red carpet she said she would try to come back, but never did. Helen Mirren waved from across the street.

"Greta Gerwig spent a lot of time greeting fans, signing and posing for pictures."

The film is a remake of the popular 1981 film, which tells the story of drunken Millionaire Playboy Arthur Bach.
