One of the best comedies of the 1970s, Blake Edwards's ode to midlife crisis and the hazards of infidelity now plays like a valentine to that self-indulgent decade, and it's still as funny as it ever was. In the signature role of his career (along with "Arthur"), Dudley Moore plays a songwriter with a severe case of marital restlessness, and all it takes is a chance encounter with Bo Derek (in her screen debut) to jump-start his libido.
