As if there weren’t enough amazing movies dropping this summer, now we’ve got the chilling first trailer for The Snowman, a thriller starring Michael Fassbender, set to hit theatres this fall.

Based on the book of the same name, The Snowman follows a detective (Fassbender) as he investigates the strange disappearances of several victims right after the first snowfall. Suspecting a serial killer, he and another detective must move fast to crack the case before the next snowfall hits.

Sooo, if you were thinking this was a Frozen-esque movie about Olaf running around doing cute things, think again. Snowmen are now scary, okay?

Directed by Tomas Alfredson  and executive-produced by Martin Scorcese, you will not want to miss this – check it out when it premieres on October 20.
