Shanghai Blues(1984)

Overview:

In 1937 Shanghai, a soldier and a young woman have an awkward meet-cute in darkness under a bridge as they seek refuge during a bomb raid. Ten years later, the soldier, now a burgeoning songwriter and tuba-player in a marching band, is back in town desperately searching for his would-be soulmate. As fate would have it they end up living in the same building unbeknownst to each other. Through a series of mishaps, he mistakes her new ingénue roommate for his love interest and wacky love triangle hijinks ensue.
