You may want to think twice before poking your head in the next passing stroller. You never know if it might be harboring a terrifying zombie baby.

As a promotion for the upcoming horror film "Devil's Due," filmmakers made a remote-controlled stroller with a horrifying animatronic "devil baby" to scare the bejesus out of unsuspecting New Yorkers.

As people approach the unattended stroller, lured in by the sound of a baby crying, the devil infant springs up and screams bloody murder. The obscene baby also projectile vomits and makes vulgar hand gestures. The reactions are priceless.

"It was screams followed by tons and tons of laughter," Sam Pezzullo, one of the video's producers told ABC News.

The prank was captured with hidden cameras and uploaded to YouTube on Tuesday. The video has gone viral, garnering more than 5 million views.

The company that made the video, Thinkmodo, are the same minds behind the prank video for the "Carrie" remake back in October. Producers said the idea for a demonic baby for "Devil's Due" was a natural fit.

"We like to take an element in the film and recreate it in real life," said Pezzullo, who works for Thinkmodo.

"Devil's Due," distributed by 20th Century Fox, is about a woman who is pregnant with the spawn of Satan.

"We thought, what if that baby went on a rampage?" Pezzullo said.

Judging by the video, what happens is a lot of screams and a lot of laughter. "One guy actually wet his pants," Pezzullo said.

The video was shot over several weeks in Manhattan and people warmed up to the demonic baby once they realized it was all a hoax.

"After that initial shock they had a great sense of humor," Pezzullo said. "They were mostly impressed by the realism of the baby." he said.

"Devil's Due" is out on Jan. 17. Hopefully, the movie is just as entertaining as the prank.
