And aside from the smiley emoji following his note, the Fault in Our Stars headliner decided to make fans work to find out about his newest movie role.
Elgort has, according to Deadline.com, signed on to 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.
The 20-year-old actor, like Van Cliburn, tickles the ivories and believes in the power of music. He has an entirely separate Twitter account, @Ansolo_Music, that promotes the "dance music" he produces independently. "Music is better than any drug," Elgort declares in the account's description. We're sure Van Cliburn would have agreed.
The pianist died of bone cancer last year. He was 78.
