It Happened at the World's Fair on AllMovie

This Elvis Presley vehicle is close to a lemon, even for his die-hard fans. Elvis is Mike Edwards, a pilot of a small plane who has a faithful sidekick, Danny (Gary Lockewood), and a penchant for singing. The story, such as it is, takes place in-between a total of ten different songs, the most memorable being "One Broken Heart for Sale". Mike is tough on the outside but he is willing to take up a good cause when he finds Sue Lin (Vicky Tiu) temporarily abandoned at the Seattle Worlds Fair. Aside from Sue Lin, he also finds an attractive nurse who is not abandoned but might still need attention.
