Leave it to Lifetime to swoop in and make a movie based on a true and tragic event. The network announced on Monday that it will be making a movie based on Chris Watts, the Colorado dad who killed his pregnant wife and two daughters last year.

"The Chris Watts Story," a working title for the film, is based on real-life events and taped confessions and "will chronicle the months that led up to the horrific crime, piecing together the Colorado dad’s possible motives," according to People, who exclusively broke the news.

The Lifetime movie, set to premiere in 2020, is produced by Sony Pictures Television and boasts an impressive cast. Sean Kleier ("Odd Mom Out") has been cast as Chris, Ashley Williams ("How I Met Your Mother") will play his wife Shanann Watts, and Brooke Smith ("Ray Donovan") will play FBI agent Tammy Lee.

"The Chris Watts Story" isn't the first film based on the tragic murders. In June, Investigation Discovery aired a documentary that explored the ins and outs of the Watts case.

On Aug. 13, 2018, Watts strangled and killed Shanann who was 15-week pregnant with their unborn son, Nico. He then proceeded to do the same with their two young children, 4-year-old Bella, and 3-year-old Celeste.

Watts is currently serving life sentences for the murder of his family in a Wisconsin prison.
