Behind the scenes of "Splitting Heirs," Catherine Zeta-Jones delivers a performance that's anything but 'heir'-archical. The Welsh enchantress strips down, her curves commanding the camera's undivided attention. She teases, she tantalizes, her every move a dance of seduction. The set is her playground, and she's the queen, ruling over every inch with a raw, unbridled sexuality that's as captivating as it is forbidden.
