Flawless (2007)

Crime drama set in swinging sixties London, starring Demi Moore and Michael Caine as workers at a large diamond trading company who conspire to steal a handful of diamonds from their employers. Laura Quinn (Moore) is an executive at the company who is becoming increasingly frustrated in her position as men of lesser calibre are repeatedly promoted above her, while Mr Hobbs (Caine) is a janitor who goes virtually unnoticed by company directors but has an in-depth knowledge of the modus operandi of the company after his many years of service there. However, what Laura doesn't realise is that the grudge-bearing Hobbs is planning a bigger heist than she imagined, and with sleuth-like insurance agent Finch (Lambert Wilson) hot on their trail, the net is closing fast...

The story is based on a fictional heist, but the film is faithful to its setting. Beautiful costumes and sets and strong attention to detail instantly transport viewers back to a different era. Moore's performance may feel wooden at times, but this is fitting considering the obstacles a woman in her position and time would have been up against. Her acting chops come through when she finally breaks down, only to have to pull herself back together for a room full of her male colleagues. Caine seems predictably at ease in his role as Mr. Hobbs, who drives the plot from behind his unassuming mop and duster. Though slow-moving at first, this stylish thriller slyly draws its audience in as its characters take on more depth.
