Query: An Almost "Flawless" Thriller

Flawless is a very enjoyable slow-burning caper starring Demi Moore and the inimitable Michael Caine. Demi Moore stars as a top female executive in the 60's diamond industry that is stymied by her gender. Caine is an affable night janitor at the diamond depository with a plan. After Caine gives Moore evidence that her termination is imminent - the two hatch a plan to rob the diamond vault.Flawless was a surprisingly enjoyable heist film and I recommend it. It is not action packed, but a slow moving intelligent thriller with a twist ending.
