Mark Strong said that the lessons of World War I could be forgotten.
The 56-year-old actor said today's people "have absolutely no idea what it must have been like to fight during the conflict.
At the premiere of Sam Mendes' Kriegsepos 1917 in London, he told PA news agency, "It's a fantastic movie to understand what this generation has gone through.
"We have absolutely no idea what it must have been like to live, be summoned and fight during this time."
When asked if he thought that teaching could be forgotten, he said, "As he drifts more and more into the distant past, yes. I think it needs people who continue to tell stories. "
Strong stars as captain helping two young soldiers (George MacKay and Dean-Charles Chapman) on their journey through enemy territory.
He said, "All the characters in it stop on the way of these boys.
"Colin Firth gives them a command and they end up seeing Benedict Cumberbatch's character.
"On the way, they meet a lot of people and one of them is Captain Smith, who meets them at a very important time and basically helps them on their journey.
"I think he is one of the few people on their trip who are really friendly to them."
