Actors who are "triple threats"--they can really sing, really act, and really dance.

When did he act, outside of a courtroom?

Hugh Jackman at the Tony’s

He was in The Wiz (musical), Captain Eo (for Disney World, I think), the Thriller video (OK, it was just a music video, but it was the first real long-form music video with story line and what-not), and probably some other stuff. I don’t think he’d ever be up for any kind of acting award had he lived, but he was an actor.

Frank Sinatra could sing reasonably well? REASONABLY WELL!

That’s a woosh isn’t it?

He didn’t sing. He crooned.

Bobby Darin.
