Carla Gugino has revealed she has been sworn to secrecy about her role in New Year's Eve.
The Sucker Punch star is among the ensemble cast for Pretty Woman director Garry Marshall's sequel to romantic comedy Valentine's Day, set on New Year's Eve in New York.
Carla said: "I literally signed a a confidentiality agreement, but I can tell you that Seth Meyers and Jessica Biel are in the same story together."
In Valentine's Day Jessica Biel played a romance-hating workaholic who found love with Jamie Foxx's equally cynical character at the end of the film.
Carla said: "Working with Garry was great... He was an actor in race to Witch Mountain as well, so I know him from before."
New Year's Eve also stars Ashton Kutcher, Sarah Jessica Parker, Robert De Niro and Hilary Swank.
