Under-rated
I'll join the small chorus that lists this as one of the better Elvis vehicles, despite the low imdb user ratings.
Wearing a black leather motorcycle jacket, Elvis still has a chip on his shoulder for most of this film. He's not yet squeaky clean as he would become in films like Clambake or Fun in Acapulco.
There's also something non-mainstream about the setting in the carnival, as compared to the luxury hotels or beach fronts where many of the other movies are set.
Two other things to like: Barb Stanwyck remains a solid pro - as ever - plus I love the scenes with Pat Buttram as the fast-talking Harry Carver.
Finally, we don't have to contend with any cutesy kids that often distracted the King in many other Elvis flicks.
Put it all together and it's a lot of fun and a little leaner than the Elvis movies that would follow.
