Wicker Park (2004)

The Chicago-set Wicker Park (2004) tells the story of discontented ad executive Matthew (Josh Hartnett), who's presently engaged to be married but forever mourning the loss of his relationship with Lisa (Diane Kruger) two years prior. Lisa didn't exactly break up with Matthew—she just vanished without a trace. Tension mounts when Matt thinks he's spotted Lisa in a restaurant, and he abandons his life in a mad scramble to track her down—only to be infinitely more confused by what he finds. With sexy turns from both Diane and Rose Byrne, Park will make your wicker thicker.
