But the defense said Monday in opening statements that the only culprit was the man already convicted in the shooting.
Brancato, 32, is charged with second-degree murder in the 2005 death of Officer Daniel Enchautegui (En-chow-TAY'-gee).
The other man, Steven Armento, was convicted of murder on Oct. 30 and has been sentenced to life in prison without parole.
Brancato made his debut in 1993 in "A Bronx Tale" opposite Robert De Niro. He's appeared in more than a dozen other movies and played a doomed aspiring mobster in HBO's "The Sopranos."
