Another self-regarding screenplay from Andrew (The Truman Show, Gattaca) Niccol, but Al Pacino is on hand to paper over the concept's cracks. A director whose prima donna (Winona Ryder) walks out, he simulates virtual actress S1mOne ("hmm, less Streep, more Bacall"), who becomes a global superstar. Could go further, but the comedy's smart and the acting, ironically, is great.
