Perhaps I was in a very forgiving frame of mind but "Harum Scarum" went down pretty well. Widely regarded as one of the King's worst offenders and he was disappointed with the results as he thought (before reading the finished script) that this would be a welcome change of pace from his established formula.
The scenery is a breath of fresh air (though we all know it's MGM's back lot for the most part) and the film has a bit more of a plot than usual; although it's very clumsily handled. The comedy bits are fairly lackluster and the action is rather stiff but the film moves along well with few to no lulls. Elvis has a strong presence but he really doesn't strain himself too much and he receives little support from his fellow co-stars; though Billy Barty (most memorable as J.J. MacKuen from "Foul Play") does induce a few chuckles without a line of dialog.
The songs range from pedestrian to very good ("Kismet" and "So Close (Yet So Far) From Paradise") and the girls, as almost always is the case with Presley films, are quite the eye candy.
"Harum Scarum" is not good but it's breezy enough entertainment for fans of Elvis that's not quite as bad as it's reputation suggests. I'd choose this over "Stay Away, Joe" any day of the week.
