The latest big name to sign on to Rian Johnson's thriller "Knives Out" is Oscar winner Christopher Plummer.

The stellar cast already includes Daniel Craig, Chris Evans, Lakeith Stanfield, Michael Shannon, Don Johnson, Jamie Lee Curtis, Toni Collette and Ana de Armas.

Craig stars as a modern-day detective on a more than usually mysterious case.

As with the rest of the cast, we don't know what role Plummer will play. But, for what it's worth, he did once play a Jack-the-Ripper-hunting Sherlock Holmes in 1979's "Murder By Decree."

Production began this week on the film, which is said to be in the vein of Johnson's films "Looper."

Plummer last starred as billionaire J.Paul Getty in the Ridley Scott drama "Beginners."
