After constant promotions for their newest film, the stars of “The Dark Knight Rises” were spotted having some fun at an after-party in London, England on Wednesday night (July 18).

Held at The Freemasons Hall, Catwoman cutie Anne Hathaway dressed in a lovely white cocktail dress as she joined castmates Tom Hardy, Marion Cotillard, Joseph Gordon-Levitt and director Christopher Nolan for a night of post-red carpet celebrations.

Also on hand at the event – which was held after the film’s Odeon Leicester Square European premiere – was Prince Harry and “The Girl with the Dragon Tattoo” actress Noomi Rapace

With “The Dark Knight Rises” set to hit theaters on July 20th, director Nolan recently spoke with USA Today about picking Miss Hathaway for the Catwoman role.

Of this, Christopher revealed. “The thing that clicked for me was trying to build a credible character from the ground up, a classic femme fatale and grifter. Anne can present a psychologically real characterization. And she can fill a room with her energy and presence.”

The 41-year-old added, “I told her that the character wears a lot of armor, in a sense, and has a strong way of dealing with the world, and that has to come from a defensive position.”

As for the famed Catwoman outfit, Anne was relieved once she was able to take it off for good, telling, “After I finished the rooftop fight, I ate four slices of pizza and split a bottle of red wine with my guy. I hadn’t eaten like that in months. I felt so ill. By the time the movie finished, I decided to give veganism a try. You can’t go hog-wild as a vegan. You can eat a lot of pasta and have a few vegan pastries.”
