I am currently rewatching
Kiss Kiss, Bang Bang. This is a movie made during a time where Robert Downey Jr. wasn't that famous yet, and he's still funny. I like watching movies like this because if I feel I can learn a thing or two from how to converse professionally like that, it's a good thing to add to your grammar arsenal. Course, I watch it in subtitles because sometimes they convey the sentences so quickly that I need to pause or stop it to understand exactly what they were trying to say.
Also, looking up on Takeshi Kitano's old films. There was a movie he made called "A Scene by the Sea". I would say it's interesting for AD'ers because both the protagonist and antagonist are deaf mute in the movie.
