The House with a Clock in its Walls begins when 10-year-old Lewis (Owen Vaccaro) loses his parents in an accident and is sent to live with his estranged and eccentric uncle, Jonathan (Jack Black). Lewis soon discovers that his uncle is a good (though not very skilful) warlock. With the help of his witch neighbour, Mrs Zimmerman (Cate Blanchett), Jonathan has been searching for a doomsday clock, which has been hidden somewhere in his house by the evil warlock Isaac Izard (Kyle MacLachlan).

When Lewis borrows his uncle’s forbidden book of dark spells to impress his new school friend Tarby (Sunny Suljic), he accidentally brings Isaac back from the grave. Lewis, Jonathan and Mrs Zimmerman must now race to find and destroy the clock before Isaac and his wife Selene (Renee Elise Goldsberry) bring about the Apocalypse.

Ideas to discuss with your children

In The House with a Clock in Its Walls Eli Roth brings to life the children’s novel of the same name by John Bellairs.

The House with a Clock in Its Walls is entertaining and well made, and slightly older children and adults who enjoy spooky movies and Jack Black comedies will like it. But it has supernatural themes, physical transformations, and depictions of death. This means it’s likely to frighten children under eight years and isn’t appropriate for children under five years. Although the movie’s supernatural and horror themes are low impact, it’s important to be aware of these themes if you’re thinking of taking children under 10 years to see this movie.

These are the main messages from this movie:

  • Difference can be a strength.
  • Accept others for who they are, and don’t try to change to please others.

The House with a Clock in Its Walls could give you the chance to talk with your children about real-life issues like:

  • gambling, specifically poker
  • house rules, including why children can’t eat cookies for every meal.
