Oscar Isaac Says Unforgettable 'Ex Machina' Dance Scene Was Cut in Half

If you have yet to see Ex Machina, GO. Right now. We’re serious.

If you have seen it, then you understand why we can’t stop smiling at Oscar Isaac’s epic dance scene.

ETonline caught up with Oscar about our new favorite sci-fi thriller, and while the overall tone of the movie is quite serious – we had to take a moment to talk about Oscar’s seamlessly choreographed dance moves.

“I cannot take credit for any of that,” said Oscar. “[It was done] by a choreographer who had won Mr. Disco in the U.K. in the mid-‘90s, so he knows his stuff.”

And that unforgettable dance scene was originally double the fun.

“It was about twice as long originally,” Oscar said. “And in the film it’s cut to about half.”

In the film, Oscar plays Nathan, a genius and CEO who brings in a programmer from his company (Domhnall Gleeson) to test an artificially intelligent Robot that he’s developed, named Ava (Alicia Vikander).

Even more extraordinary than Ava in the film, is the work that went into her behind the scenes. Oscar explains how Vikander was covered from head-to-toe in a grey mesh suit during shooting, and edited in post-production to remove her mid-section, her neck, and add the necessary robotics -- a process that had little interference with filming.

“It is amazing how far [technology has] come as far as visual effects,” said Oscar. “On set there was no intrusion whatsoever, we could just play the scenes as is.”
