The movie is adapted from The House with a Clock in Its Walls gothic horror novel. It was written by John Bellairs and originally published in 1973. Starring Jack Black, Cate Blanchett, and Kyle MacLachlan, along with introducing Owen Vaccaro, the movie looks heaps of fun.
In the latest trailer, we can see Black and Blanchett reveal themselves as powerful controllers of magic who attempt to teach Vaccaro’s young character their ways. However, the last tenant of their spooky mansion installed a clock in the walls (hence the title) which is counting down to something ominous happening.
