Rachel Weisz has taken herself off the action/adventure, The Mummy 3 for Universal Pictures, says The Hollywood Reporter.

The Oscar-winning actress has opted not to join her returning co-star Brendan Fraser in the film, which Variety is reporting has officially signed on. The third installment of the series takes place in China, and will introduce Jet Li as the villain; Rob Cohen is directing.
