Jennifer Garner is jumping into the lead role for a new Apple TV+ limited series titled The Last Thing He Told Me, Deadline reports. Garner, who will also serve as an executive producer, will be stepping in for Julia Roberts who was cast in the lead role, but had to step back due to scheduling issues. Reese Witherspoon’s Hello Sunshine will produce the series with Witherspoon representing the studio along with 20th Television.

Based on the story from The New York Times #1 bestseller by the same name written by Laura Dave, the Apple TV+ adaptation will center around the story of a woman (Garner) whose husband’s unexplained disappearance leaves many questions unanswered. While sorting out the truth from the lies of this bizarre occurrence, the woman creates an unlikely bond with her 16 year old stepdaughter. Published by Simon & Schuster, the novel has sold over 1.3 million copies to date and has clocked in over six months on the New York Times bestseller list.

The series is created by Dave and co-created by Oscar winner Josh Singer (Spotlight), who are a married couple. The married team also serves as executive producers alongside Witherspoon and Lauren Neustadter who will be representing Hello Sunshine.
