Jennifer Garner replaces Julia Roberts in Apple TV+ original 'The Last Thing He Told Me'

Garner will star and executive produce the limited series produced by Reese Witherspoon's Hello Sunshine, which optioned Laura Dave's New York Times bestselling book, Deadline reported Friday.

The adaptation tells the tale of a woman (Garner) who forms an unexpected relationship with her 16-year-old stepdaughter while unraveling the mystery surrounding her husband's disappearance. Roberts was originally slated to star in the lead role.

"The Last Thing He Told Me" was created by Dave alongside her husband Josh Singer, who won a Best Original Screenplay Oscar for "Spotlight." Lauren Neustadter will executive produce with Witherspoon for Hello Sunshine.

Garner is also starring in and executive producing an Apple TV+ adaptation of Amy Silverstein's memoir "My Glory Was I Had Such Friends." Bad Robot's J.J. Abrams and Ben Stephenson are attached to the project as executive producers.

Apple TV+ is slowly building out an impressive library of content with series, films and specials spanning a range of genres. The tech giant reportedly plans to double its production slate to release one new show or movie a week in 2022.
