How old was Maggie Smith in Keeping Mum?

Knowing a celebrity’s age during a specific movie can be oddly satisfying. That knowledge can reshape how we view their performance. Here’s the age that matched the moment.

During the filming of Keeping Mum, Maggie Smith was:

70 years old

That’s the confirmed age we calculated for the celebrity in that role.

The calculation of the shown age took into account the first day of the year in which the movie Keeping Mum was released:

January 1, 2005

And the day Maggie Smith was born, which is:

December 28, 1934

Because movies often premiere within a year of starting production, Maggie Smith might have been either one year younger or older while filming some scenes.
