Meryl Streep is desperate for a rest after a string of movie roles.

The actress has starred in several films recently, including Julia and Julie, Doubt and Mamma Mia - and has admitted that she is now "exhausted".

"Seven movies in two and a half years. I have never worked this hard ever. I am exhausted, I'm feeling like I need a break.

"Promoting movies is not fun. The most fun part is making the movies. Selling a movie is more to do with wardrobe and shoes and cleaning up and being presentable."

She added, "I haven't ever considered giving up acting, but I do need enforced rest in my career. When each of my children was born I took a year off. It is very nice to have time to live, gather experience and watch people."

Streep and her husband, Don Gummer, have four children together.
