But its been so interesting.

Its a shoot-em-up film cars crashing, killing people but its choreographed,butwith a straight face.

There are certain dance elements in the film, says Heffington.

The whole scene tends to be timed out, so thats been my job.

I researched [Edgar] after I had my first interview, says the choreographer.

I tend to take on projects that I havent done before, or are experiences I havent had before.

I was like, Okay, theres no way Im not going to do it.

It sounds like a really cool adventure.

And it has been.

Edgar is great to work with and hes so meticulous.

I mean, he knows my choreography better than I do.

I mean, most directors do, but not to this degree.

Its a three-minute one-take and it involved probably 50, 60 extras.

Ansel exited a building and he goes on this journey.

To have a three-minute one-take was challenging, but it was so fun.

It was pretty special.

Heffington was helped by the fact that both Elgort and Foxx have dance experience.

Jamie can sing, he can dance half the time hes like, I got this!'

said the choreographer, with a laugh.

Thats whats so impressive.

Ansel has a dance background as well.

He really gets to let loose.

Hell be dancing his ass off in that space.

We had one rehearsal so far and he is killing it.

So, on his next choreography job, will Heffington be suggesting the addition of car chases and gunplay?

…jumping off buildings, yeah, he said.

Check that one off!
