Consider this 1964 musical a sex-symbol summit of the highest proportions. On one side, Elvis Presley, pairing on screen, for the first time, with a singing sensation as full of gyrations and sexual energy as himself. On the other side, Ann-Margret, about whom you could say, “Ditto.” Do the sparks fly? In the musical numbers, most definitely. The rest of the time? You decide.
