Actress to co-star with Josh Brolin and Anthony Hopkins

Woody Allen has his gal.

Naomi Watts has been cast in Allen's latest untitled project opposite Josh Brolin and Anthony Hopkins. The Allen-scripted film will shoot in London this summer.

No plot details have been released.

Letty Aronson, Steve Tenenbaum and Jaume Roures are producing the film, which the Spain-based Mediapro is financing. Allen and Mediapro partnered on "Vicky Cristina Barcelona," which has grossed $51 million worldwide since its 2008 opening.

Allen's comedy "Whatever Works" will be released domestically by Sony Pictures Classics on June 23.

Watts, repped by CAA and Untitled Entertainment, most recently starred in the thriller "The International." She is currently filming Rodrigo Garcia's "Mother and Child."
