Although the words "film" and "movie" are sometimes used interchangeably, "film" is more often used when considering artistic, theoretical, or technical aspects, as studies in a university class and "movies" more often refers to entertainment or commercial aspects, as where to go for fun on a date.

A "DVD" is a digital format which may be used to reproduce an analog film, while "videotape" ("video") was for many decades a solely analog medium onto which moving images could be recorded and electronically (rather than optically) reproduced. Strictly speaking, "Film" refers to the media onto which a visual image is shot, and to this end it may seem improper for work in other "moving image" media to be referred to as a "film" and the action of shooting as "filming", though these terms are still in general use. "Silent films" need not be silent, but are films and movies without an audible dialogue, though they may have a musical soundtrack. "Talkies" refers to early movies or films having audible dialogue or analog sound, not just a musical accompaniment. "Cinema" either broadly encompasses both films and movies, or is roughly synonymous with "Film", both capitalized when referring to a category of art.

Any film may also have a "sequel", which portrays events following those in the film. Bride of Frankenstein is an early example. When there are a number of films with the same characters, we have a "series", such as the James Bond series. A film which portrays events that occur earlier than those in another film, but is released after that film, is sometimes called a "prequel", an example being Butch and Sundance: The Early Days.
Credits is a list of the people involved in making the film. Before the 1970s, credits were usually at the beginning of a film. Since then, the credits roll at the end of most films.
A Post-credits scene is a scene shown after the end of the credits. Ferris Bueller's Day Off has a post-credit scene in which Ferris tells the audience that the movie is over and they should go home.
