Stardom is a loose word, but Sergej Onopko is a clear case of a star actor whose face is familiar even to people who have not seen the films. 'A Good Day to Die Hard' counts among the most-seen credits. 28 was the age at the first credit. More credits fall under thriller than under anything else. In 13 years the count has reached 23 titles. The film 'Don't Breathe' does more for the public profile than the rest of the filmography combined.
