ELVIS PRESLEY gets to sing several non-memorable songs, the best of which is "One Broken Heart for Sale", but IT HAPPENED AT THE WORLD'S FAIR is strictly standard Presley stuff wherein the guy has his eye on a pretty gal (JOAN O'BRIEN) and makes a pitch, the sort that turns her off at first. Predictably, after a few misunderstandings involving a small girl abandoned at the fair, a happy ending is soon in sight.
The music by Leith Stevens is pleasant enough and the fair grounds at the 1962 Seattle World's Fair make colorful backgrounds for the slight story. GARY LOCKWOOD is Elvis' pilot pal, both of them down on their luck but seeming to spend plenty of money on the fair and decent lodgings. The sub-plot involving both bachelors entrusted with the care of a seven year-old by a complete stranger is more than a little improbable, especially given today's public awareness of children being taken advantage of by adults with criminal behavior.
Presley shares some effective scenes with the little girl but has his standard "boy meets girl, boy loses girl, boy wins girl" routine with leading lady O'Brien, a pert blonde who plays a nurse who suspects him of feigning illness as a part of his wolf routine. Naturally, the little girl is responsible for bringing them together again after a few silly misunderstandings keep them apart.
Nothing special, but passes the time pleasantly whenever Elvis sings, which is pretty often.
