Watch: Final 'Fantastic Beasts and Where to Find Them' trailer brings all the magic and then some

If you had any doubts about this being a blockbuster, the final trailer for 'Fantastic Beasts and Where to Find Them' should quash them immediately.

While previous trailers had hinted at just a bit of magic and magical creatures causing havoc in 1920s New York, this one really shows how it's all going to hell after Eddie Redmayne's Newt Scamander accidentally unleashes some of his fantastic beasts on the city.

Also starring  Katherine Waterston, Dan Fogler, Alison Sudol, Colin Farrell, Ezra Miller and Jon Voight, this much darker and more action-packed trailer hints at the events of the film having much larger and far consequences than previously thought, so expect this part of the Harry Potter franchise to run and run (until the cast get too expensive).

'Fantastic Beasts and Where to Find Them' is released in cinemas on November 18th.
