Pacino turns Nazi hunter in TV series debut for Amazon
In a screen career spanning more than five decades, it has taken Al Pacino until now to act in a television series.
He is starring in "Hunters", a new show for Amazon Prime that is due to be released on Friday (February 21).
The series, about a band of Nazi hunters in New York in the 1970s, is inspired by a true story - a "love letter" to the show creator's late grandmother who survived Holocaust.
"I never did this sort of long 10 episodes.
So it's like doing like, I think, about a 12-hour film because it is about 12 hours of film," Pacino, who turns 80 in April, told Reuters.
"This is a crazy story, too, by the way ... Crazy horror, really scary stuff.
And also heavy, deep, tragic emotion ... it runs the gamut," said Pacino, who was nominated for Best Supporting Actor at this month's Academy Awards for his role in "The Irishman".
