Where is Capturing Mary? Not a theatrical release but Dame Maggie is all-in. Gosford Park and Quartet were not "phoned in", among others.
At her best, one of the world's great actresses. At her worst, she's just showing up for the paycheck.
She's been cashing a lot of checks in the last 20-30 years...
There are some few films missing In the Mubi list with Maggie Smith, such as Mankiewicz's "The Honey Pot", "Othello", "The V.I.P.s" or Ladies in Lavender".
