"An animatronic "devil baby" in a remote controlled stroller goes on a rampage through the streets of New York City and hidden cameras record people's reactions."

That's how the makers describe this video.

A crying baby can be heard from the abandoned buggy and any concerned passer-by who has a look to see inside gets a realistic, nightmare baby in their face.

He chases people down the street, gives the police the finger and even projectile vomits on people.

This viral marketing campaign video made by Thinkmodo is to promote the horror movie Devil's Own which is released in Ireland on the 17th January. 

The reactions, if real, are priceless...
