Scarlett Johansson's performance in 'Under the Skin' is perhaps best known for one where she is naked frequently. And, while that might be all you really need to know about 'Under the Skin,' there is also this interesting tidbit. For the film, where Scarlett plays a beautiful-but-evil man-killer, the actress secretly went out, seduced regular guys walking down the street and lured them into a van.

Johansson told reporters at the Toronto Film Festival that director Jonathan Glazer had the radical idea for the trippy thriller. He, along with the DP, the assistant director and a sound guy sat in the back of the van while Scarlett wore an earpiece and went out on the street to try and convince random dudes to come into the back of a van with her.

"It was really terrifying, actually," Johansson told Vulture. Uhh, ya think so?

Luckily, none of the guys she approached were complete lunatics, nor did any of them recognize her as Scarlett Johansson. [Who are these people? Any why are we never these people in these situations?] After their scenes were shot surreptitiously, the lucky ducks were all informed they had been filmed for a movie and signed a waiver approving their appearance in the movie.

So, a lesson to you all: if a woman who looks like Scarlett Johansson comes up to you on the street and asks you to get in the back of a creepy van...well, you still probably shouldn't do it. But definitely at least think about doing it.
