Holmes signs on for 'All My Sons'

The worst kept secret on Broadway is no longer a secret - Katie Holmes will star in the upcoming revival of playwright Arthur Miller's 'All My Sons'.

The 'Batman Begins' star will join a cast that also will include John Lithgow, Dianne Wiest and Patrick Wilson.

The drama, about a family patriarch's darkest secret, was Miller's first big hit and is beloved by thespians and theatre critics throughout the world.

It will mark the first time a Miller play has been staged on Broadway since the writer's death in 2005.

The play will also be Holmes' Broadway debut.
