Devil baby scares New Yorkers in viral PR stunt for new horror film

The red-eyed robotic tot screams and vomits in promotion of Devil's Due

Unsuspecting New Yorkers are under attack from a bizarre force of evil this week. (Scroll down to see the video.)

A demon baby in a parentless pram has been let loose on the streets as part of a viral publicity campaign for new horror movie Devil’s Due, released on Friday.

As people approach the remote-controlled buggy to check that the child inside is alright, the possessed robotic baby shocks them by sitting up suddenly and screaming blue murder.

On a deadly mission to destroy, 'devil baby' chases people as they run away and projectile vomits.

The entertaining reactions have been captured on video and shared on YouTube, but Mashable has reported that the surprise may be feigned, as is common with viral videos.

The synopsis for Devil's Due reads: "After a mysterious, lost night on their honeymoon, a newlywed couple finds themselves dealing with an earlier-than-planned pregnancy.

"While recording everything for posterity, the husband begins to notice odd behaviour in his wife that they initially write off to nerves, but, as the months pass, it becomes evident that the dark changes to her body and mind have a much more sinister origin."

Another recent film marketing stunt involved a woman using 'telekinetic' powers in a coffee shop in October, ahead of the remake of Stephen King's 1974 horror novel Carrie.

After a customer spilled his hot drink on the lady’s computer, she pinned him against a wall and used her supernatural skills to move him up towards the ceiling.
