Amanda Seyfried joins 'Woman' cast

To star opposite Annette Bening in Oscar Wilde adaptation

Amanda Seyfried has joined the cast of "A Woman of No Importance," the Oscar Wilde adaptation that Bruce Beresford is directing for Myriad Pictures.

Seyfried will star opposite Annette Bening in the class comedy, playing a young woman who falls victim to the mischievous games of a group of upper-crust members of British society.

The actress broke out as the daughter with an unknown father in the 2008 musical hit "Mamma Mia!" and is set to star in the romantic drama "Dear John" for Relativity and the Diablo Cody-penned "Jennifer's Body" for Fox Atomic.

Additionally, Myriad has signed director Ernie Barbarash to direct "Hybrid," its comic-book actioner involving college students haunted by a deep-sea monster. The project grew out of a first-look deal with Studio 407.
