While Tim Curry's version for the 1990 TV movie favoured a colourful, sneak attack approach to its true nature, it appears director Andy Muschietti (Mama) and costume designer Janie Bryant (Mad Men) have gone for timeless terror.
"The costume definitely incorporates all these otherworldly past lives, if you will," Bryant tells Entertainment Weekly. "He is definitely a clown from a different time. There is almost a doll-like quality to the costume. The pants being short, the high waistline of the jacket, and the fit of the costume is a very important element. It gives the character a child-like quality."
It is a demonic creature that preys on the fears of a group of children in a small Maine town. We will follow the characters as kids in the first of the two planned films, before the second finds them grown up with no memory of Pennywise, but forced to confront their past when it returns. The initial casting also includes Jaeden Lieberher (Midnight Special), Finn Wolfhard (Stranger Things), Jack Dylan Grazer (Tales Of Halloween), Wyatt Oleff (Guardians Of The Galaxy), Chosen Jacobs and Jeremy Ray Taylor (42).

It – or at least the first part – will arrive in cinemas on 8 September next year.
