A man accused of fatally stabbing a movie producer's son at a Beverly Hills home has pleaded not guilty to murder.

Scott Barker entered the plea Monday in Superior Court. He could face the death penalty if convicted.

Prosecutors say Barker stabbed 21-year-old Katsutoshi "Tony" Takazato last week at the victim's home in the wealthy Trousdale Estates area. Takazato's father, Fuminori Hayashida, lives in Japan and produced several movies in the 1990s, including "Lured Innocence" starring Dennis Hopper.

Prosecutors say Barker was dating Takazato's former girlfriend and became enraged after she claimed Takazato had physically abused her.

The woman, Chie (CHEE) Coggins, also has pleaded not guilty to murder.

Barker and Johnson remain jailed on $3 million bail each.
