Los Angeles: Actor Ansel Elgort, who has been winning hearts with his role in weepy teen romance `The Fault in Our Stars`, has signed on to play an American pianist in the Cold War-set drama.

"Some news on the movie front," Elgort tweeted.  The 20-year-old actor will play Van Cliburn, an American pianist who won the Tchaikovsky International Piano Competition at the height of the Cold War.

The film `Van Cliburn` is based on the Howard Reich book of the same name.  Cliburn died of bone cancer last year at the age of 78.-- PTI
