The suit had to be just right to pull off the stunts seen in the movie.
Scarlett Johansson's flawless figure is put on full display in her new movie, Ghost in the Shell, and ET has details on the silicone unitard that her character dons for much of the film.
"The thermoptic suit is really sort of a second skin and it allows her to become invisible," Johansson explained in a behind-the-scenes clip.

In the movie, the Golden Globe-nominated actress plays The Major, a special ops, one-of-a-kind cyborg hybrid who leads a taskforce in taking down a nefarious computer hacker.
The suit is a staple of the Ghost in the Shell franchise, which allows The Major to get away without leaving a trace.
With the role calling for plenty of action stunts, the suit had to be flexible enough to move with Johansson's body as she kicked and tumbled on camera.
"It wouldn't be Ghost in the Shell without the crazy fight sequences," Johansson said. "It's been really empowering."
Ghost in the Shell opens March 31.
