This is chronological list of action films released before the 1970s. Often there may be considerable overlap particularly between action and other genres (including horror, comedy, and science fiction films); the list should attempt to document films which are more closely related to action, even if they bend genres. Action films are generally considered a post-Classical Hollywood film genre. Additions to this category before the 1970s should be used sparingly, and films before the 1960s are not to be included.
