The thriller, starring Adams as an agoraphobic child psychologist who witnesses a crime, was set to hit cinemas on October 04, but it has now been pushed back to an unknown date in 2020 so it can be reworked.
According to editors at The Hollywood Reporter, Disney executives, who obtained the film when they acquired the Fox film empire in March, have opted to remove it from their 2019 slate - after early test screenings showed that the narrative confused audiences.
"We're dealing with a complex novel," said Fox 2000 president Elizabeth Gabler, who is departing the studio imminently but will remain as a consultant on the film for Disney until its release. "We tested the movie really early for that very reason. We wanted to make it better, and we've had Disney's full support in doing that."
Director Joe Wright, known for films such as "Darkest Hour" and "Atonement", is reportedly planning five days of reshoots in August, once Adams wraps filming on Ron Howard's Netflix movie "Hillbilly Elegy".
"The Woman in the Window", based on the best-selling 2018 novel by A.J. Finn, also stars Julianne Moore, Gary Oldman and Anthony Mackie, and was adapted for the screen by playwright and actor Tracy Letts.
