Elvis Presley is one of those American icons you just can’t replicate.

His electrifying chemistry with Ann-Margret lit up the screen in the 1964 film Viva Las Vegas, especially in their playful and perfect duet, “The Lady Loves Me.”

But not everything went as planned on set. There were bloopers and mistakes in the movie that slipped by unnoticed — until now. Ready to discover what you missed? Let’s take a closer look!

Elvis and Ann-Margret made movie and musical history together in Viva Las Vegas, which became the highest-grossing Elvis Presley film. Elvis Presley stars as Lucky Jackson, a determined race car driver aiming to win big in Las Vegas. Ann-Margret plays Rusty Martin, a vibrant dancer who captures Lucky’s heart.

In my opinion, it’s one of the most underrated films of all time.

Aside from the captivating performances, it also offers a rare glimpse of old Vegas landmarks that are now long gone.

The on-screen chemistry between Elvis and Ann-Margret was undeniable, and their off-screen connection was just as electric. But beyond the glitz and glamour, there are some hilarious goofs, little-known mistakes, and funny moments that even the biggest fans might have missed.

When it came down to it, Elvis clearly got the lion’s share of the musical spotlight. He had six solo numbers, while Ann-Margret only had two.

One unforgettable and sizzling dance scene in Viva Las Vegas is when Elvis and Ann-Margret hit the floor for the song ”Viva Las Vegas.” Lookin at it now, 60 years later, Ann-Margret is the embodiment of the phrase “dance like no one’s watching.”

It’s almost impossible to take your eyes off her, she just explodes with talent and charisma. Some fans have even said it’s the only time Elvis truly shared the spotlight with someone whose dancing talent could match his.

While Elvis brought his signature energy to the scene, let’s be honest — Ann-Margret’s choreography is in a whole other league. Thank you to the choreographer (the brilliant David Winters), for bringing us a dance sequence so full of life, it’s still mind-blowing.
