Christopher Plummer is in negotiations to join the cast of Knives Out, the all-star detective thriller from Rian Johnson, the filmmaker behind Star Wars: The Last Jedi.

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

MRC, the company behind movies such as Baby Driver and the upcoming Mortal Engines, is producing and financing Knives, which is said to harken back to the more singular vision of Johnson’s movies such as Brick and Looper.

Craig is toppling as a detective tasked with solving a modern-day whodunit murder mystery. Details on who Plummer, the veteran actor whose credits range from The Sound of Music to A Beautiful Mind, would play were not revealed.

Production began this week.

Plummer last starred in the Ridley Scott drama All the Money in the World. Stepping in at the last minute for original star Kevin Spacey, Plummer played billionaire J. Paul Getty in scenes reshot prior to the movie’s release. The performance earned him an Oscar nomination.

He is repped by ICM Partners and the Pitt Group.

Media Rights Capital (MRC) is owned by Valence Media, which is also the parent company of The Hollywood Reporter.
