Harold and Maude: How old is Maude?

Question

She looks really old!

Answer 1

The film takes place just before her 80th birthday and ends on her 80th birthday.

Did you watch it?  How could you miss that?

The actress who played Maude, Ruth Gordon, was probably in her 60s when the film was made.

Answer 2

Ruth Gordon, who played Maude, was born 30 October 1896 and the movie was made in 1971, so she would have been 74 or 75 then.
