Cheyenne, a retired rock star living off his royalties in Dublin, returns to New York City to find the man responsible for a humiliation suffered by his recently deceased father during W.W.II.
The conceit of showing a pop-culture figure's life out of the limelight is beyond hackneyed, but the film's incongruous visual splendor and Penn's all-or-nothing commitment keep Sorrentino's unabashed folly afloat for a while.
As oddly magnetic as Sean Penn's performance is, the film seems more preoccupied with being quirky and puzzling than with telling a cohesive, satisfying story.
