Canadian filmmaker Atom Egoyan's latest film "Remember" has premiered at the Venice Film Festival Thursday.

He was joined on the red carpet by some of the film's stars including Bruno Ganz, Jurgen Prochnow and Heinz Lieven.

The film also stars Christopher Plummer and Martin Landau.

The film is about an old man, who goes in search of a Nazi guard who was responsible for murdering his family some 70 years ago.

Egoyan says Plummer's acting gives the film a high degree of authenticity.

"There's no real subtext to the performance. I mean as you watch it you realize it's quite a radical performance. You don't see that very often and most of the time when you have an actor, they're playing some other interior life but he has made a choice not to do that at all. And it gives the film a very unusual tone. But because of his age, you completely buy that." "Remember" is one of 21 films competing in the main competition at the festival.

The Venice Film Festival runs until Saturday, September 12th, when the winner of the prestigious Golden Lion - the festival's top prize - will be announced.
