Patty McCormack Returns to 'The Bad Seed' for Remake Directed by Rob Lowe

McCormack, 73, was just 11 when she starred in the classic movie.

Patty McCormack was just 11 years old when she starred in the 1956 classic, "The Bad Seed" — and now she's back for more.

She terrified audiences as the demonic child Rhoda Penmark in the original movie, even earning a nomination for best supporting actress at the Academy Awards, as well as a Golden Globe nod.

Now 73, she is returning to the screen for a remake of the film, which airs on Lifetime Sunday.

"At the time, it was groundbreaking," McCormack told Inside Edition.

This time around, she plays a psychologist, while the child is played by 12-year-old Mckenna Grace. Rob Lowe, who also directed the film, plays the girl's father.

"I've always wanted to play a bad guy in a horror movie for some reason," Mckenna told Inside Edition. "So that was really exciting."

McCormack added, "It is a passing of the torch for me because it was so momentous in my life."
