Reddit mentions of Film: A Critical Introduction. Maria Pramaggiore, Tom Wallis

Those are good books but any particular one might be a little narrow focused for someone trying to get a kind of catch all beginning. If you like book learning I would more suggest a book like this. This particular one is commonly used to teach first year film studies in university classes. It gives a nice blend of instruction like "this is editing", "this is direction" etc... and instruction on film appreciation. I promise that you will learn a lot more form watching film with even a little guidance on film appreciation and how to watch movies more actively.
