It's hard to get more mediocre than If I'm Lucky, a musical remake of Thanks a Million that is relatively easy enough to sit through but which fails to make much of an impression. The original satirical thrust of Million is diluted in Lucky, and making the main character a radio star who, at least partially, gets involve din this mess to lure listeners, doesn't wash. It might if the part were written to be played in a zany and "way out" style and if it were then cast with someone other than the blandly personable Perry Como. But that is decidedly not the case, and so one watches and wonders why the filmmakers didn't either take a different route with their star or cast a different type for the picture. Como sounds great, of course, but he just doesn't have a magnetic cinema personality. Vivian Blaine comes off better, and Harry James is fun as long as he's surrounded by music. Carmen Miranda brings zest and energy, but her big solo cried out for color. And none of the musical performers have been given a song that is in the least bit distinguished. Phil Silvers gets a great deal of laughs, despite the fact that most of his jokes are weak, which says something about the man's ability.
