NEW YORK, Dec. 5 (UPI) -- Get Out and M3GAN actress Allison Williams says Morgan, the stay-at-home mom she plays in Regretting You, is forced to re-evaluate her choices after a devastating tragedy and betrayal upend her world.

"It changes, literally, everything," Williams, 37, told UPI in a Zoom interview this week.

"I think her reaction is somewhat blunted by all of her responsibilities as a mom, but I think it just fundamentally restructures her life and makes her see everything differently."

The adaptation of Colleen Hoover's best-selling novel is now available to buy or rent on digital platforms.
