He was great as Kruschchev. Everyone in that flick was great. I always pictured Beria as a lean predator type, but the rather heavyset guy who played him made him plenty evil.
The best Beria was in the movie “Stalin” with Robert Duvall as Stalin.
“Stalin said he would spare our lives”
Beria: “Comrade Stalin has revoked his promise”
I liked comrade Zhukov best. Although almost everybody except Molotov got their roles right. Stalin speaking cockney is brilliant by itself.
