What film did John Wayne say I got a saddle older than you are Mrs. Lowe?

John Wayne did not say the line "I got a saddle older than you are Mrs. Lowe". This line is from the 1953 film "The Searchers", and it is said by Ethan Edwards, played by John Wayne. However, he says it to Laurie, not Mrs. Lowe.

It is a very memorable line, and it's likely the reason you associate it with John Wayne.
