any recommendations for english language films with accurate period dialect?

interested in the historical form of the english language (middle english onwards)

here is what i have so far

1. anything shakespeare, ofcourse
2. cromwell (1970)
3. becket (1964)
4. the vvitch (2015)

series recommendations appreciated also, but the dialogue MUST be period-accurate.
also if you know any better subreddits to ask this, please tell!
