"The Marvelous Mrs Maisel" star will also executive produce along with the author.

Set in the UK, "The Switch" follows a 29-year-old consultant, and her 79-year-old grandmother, who decide to swap lives (including cell phones) for two months, after a series of personal setbacks.

While the younger woman moves to a tiny Yorkshire village to tackle the responsibilities of dog walking and neighborhood watch, the older woman finds herself in a tiny London flat, navigating dating apps and starting up a social club for lonely Londoners.

Kristie Macosko Krieger, who has produced films such as "The Post", "Bridge of Spies", and the forthcoming "West Side Story", will produce the project for Amblin.
