The project will include a scene in which Stapp will perform as Sinatra at the famed Cocoanut Grove, at a time when Ronald Reagan was president of the Screen Actors Guild and the club was a staple of old Hollywood. Reagan stars Dennis Quaid in the titular role and is planned for a 2021 release.
"Sinatra in performance mode was an exercise in restraint,” Stapp says in a statement. “He had this steely, stylish swagger and his sheer presence commanded a room. I was excited to join the cast and blown away by the on-set attention to detail, style, and overall production."
