Movies in Latin
I have just found one with subtitles in Polish, English and French. Title: Imperator, Emperor a film by Konrad Łęcki (in Latin). Link: https://www.youtube.com/watch?v=RRTh3qqZLkQ
Do you have more recommendation? :)
To add to the imdb list that dreamloomer has posted (thanks, dreamloomer!) there is also The Passion of the Christ, produced by Mel Gibson, which is in Latin, Aramaic and (IIRC) Greek. BTW, Sebatiane is said to be quite raunchy, be warned.
Related: There are snippets of films on Youtube dubbed in Latin, also a short U.S. film in Latin for high schools; links for these I'll add, if I can unearth them from my bookmarks. Some Youtube channels such as Latinitium or Paideia have short subjects or talks in Latin. You can find a fairly comprehensive list of bloggers from ScorpioMartianus; links can be found if you click on "SHOW MORE" below the video; generally the Latin is very good. The vivariunnovum Youtube channel may have some sort of short subjects, too. Several of the websites associated with these channels (also the indwelling site) have plenty of audio and/or video material in Latin, but those materials, too, are not films with a plot.
Generally the "restored" pronunciation is used, as in the Duolingo course; occasionally the ecclesiastical pronunciation is used, but the differences are not all that great and can be adjusted to fairly quickly.
There are some good speeches in well translated Latin in Destiny of Rome:
Also known as 'Rome's Greatest Battles' in the USA, this was a French production. It gets deleted from Youtube for copyright reasons but is currently here:
There is also this short from Romania, Capriciile Fortunei | The Whims of Fortune :
Magister Craft is good for Latin at an early-ish point, albeit a bit further on than the Duo course currently takes you. https://www.youtube.com/channel/UCTtKmPD0_Qo9Uy932ZGKFhA
