Kevin Pollak Says 'The Irishman' Was Great, But Stars Were Too Old

Kevin Pollak says Martin Scorsese's new mobster flick, "The Irishman," was as good as it gets for the genre -- but there was a little issue according to him ... the stars were too damn old.

We got the veteran actor right on the heels of the new flick landing on Netflix and asked for his thoughts on it ... considering he starred in Marty's "Casino" and tons of other crime movies. Turns out, he loved 'Irishman' ... with one caveat, and it's hard to tell if he's joking.

Kevin says at one point ... the film played more like a trio of old coots who lost their keys instead of menacing mobsters in their prime. He does some hilarious impressions too, to drive home his point. Pretty spot-on with his versions of Pacino, Pesci and De Niro. Well, the first 2 ... he kinda phoned it in for Bobby D.

If you haven't seen it yet, the movie captures one hit man's journey from start to end, so the actors' appearances do change a lot.

Of course, the gimmick with the film is the digital de-aging technology the 3 stars were put through -- especially De Niro.
