Robert De Niro received a lifetime achievement award at the Karlovy Vary Film Festival on Friday, where his What Just Happened? opened the festival, and discussed his plans for the future, according to Variety.

He noted that he would like to make two sequels to CIA Cold War drama The Good Shepherd -- one bringing the action forward from 1961 to 1989, the other following its hero, Edward Wilson (Matt Damon), up to the present day.

Although he is not working on research for the concluding parts of the hoped-for trilogy, De Niro said being in central Europe offered a good opportunity to begin thinking about the material.

"I had not been planning to do research on that while here, but it is a good idea," he said.

His long collaboration with Martin Scorsese -- which he ascribed to the fact it's always been "a lot of fun to work" together -- should produce at least two more films, De Niro said.

His next project with Scorsese, which he declined to detail, is one on which he's already working and should be ready by 2009, he said.
