Alessio Scalzotto and Ian Ho are also set for Babysitter's Guide, which has already begun principal photography in Vancouver.

Based on the first book in the series by Joe Ballarini from Harper Collins imprint Katherine Tegen Books, the film will follow first-time babysitter Kelly Ferguson, whose charge is kidnapped by the Boogeyman. She then discovers a secret society of fierce babysitters who protect children — and an entire world of monsters she will have to fight in order to save the child she's looking after.

Veteran television director Rachel Talalay (Dr. Who, Riverdale, Sherlock) will helm the genre family feature. Ballarini adapted his own story.

Ivan Reitman will produce for The Montecito Picture Company with Amie Karp. Tom Pollock for The Montecito Picture Company and Ilona Herzberg will exec produce, along with Naia Cucukov for Walden Media, which is also working with the streamer on The Baby-Sitter's Club series.
