Angela Lansbury’s final onscreen appearance will be in ‘Glass Onion: A Knives Out Mystery’

Angela Lansbury’s final act has yet to be seen.

The television star and theater icon, who died Tuesday at age 96, will make her last onscreen appearance in one of Hollywood’s most eagerly anticipated sequels.

“Glass Onion: A Knives Out Mystery” will reportedly boast posthumous cameos from both Lansbury and late composer Stephen Sondheim. According to Playbill, the two Broadway legends will portray themselves in the star-studded murder-mystery, fronted by Daniel Craig.

The film will hit 600 movie theaters for one week at Thanksgiving, before streaming on Netflix Dec. 23.

Written and directed by Rian Johnson, “Glass Onion,” was filmed last summer in Greece and also has an ensemble cast that includes Edward Norton, Janelle Monae, Kathryn Hahn, Leslie Odom Jr. and Kate Hudson.

The murder-mystery — about someone turning up dead when a tech billionaire invites his friends for a getaway on his private Greek island — is right in the wheelhouse for Lansbury, who famously portrayed amateur sleuth Jessica Fletcher on the long-running CBS series “Murder, She Wrote.”

Sondheim, who died in November 2021, was such a fan of the whodunit genre that he hosted murder-mystery game nights with his friends. He also co-wrote the 1973 film “The Last of Sheila” with “Psycho” star Anthony Perkins. Johnson has admitted that he was influenced by the “Sweeney Todd: The Demon Barber of Fleet Street” co-creator’s work. In 1979, Lansbury won the best actress in a musical Tony Award for her Broadway role in the beloved musical.

In the first installment of “Knives Out,” Craig’s character bellows a few bars of “Losing My Mind,” a torch song Bernadette Peters belted out in Sondheim’s 1971 musical “Follies.”

Released in 2019, “Knives Out” became a blockbuster hit, amassing more than $311 million at the box office.
