Reddit reviews A Dictionary of Film Studies (Oxford Quick Reference)

There's a documentary series called The Story of Film: An Odyssey which is pretty good for learning about some of the key filmmakers and movements from the beginning of cinema. I haven't actually watched any of this myself yet but it looks promising and the reviews are good!

There's also another book that I'd really recommend which is Oxford's Dictionary of Film Studies. It's got definitions and explanations for pretty much all the basic terminology, theories, movements, etc for film studies and they're not too lengthy to read. Most entries in the book are around a page long or less, so if there's something you'd be interested in looking up and reading about it's brief enough to not cut into your study hours but still in-depth to give a fairly detailed introduction for you.
