A live-action/animated film is a motion picture that features a combination of real actors or elements: live-action and animated elements, typically interacting.

Originally, animation was combined with live action in several ways, sometimes as simply as double-printing two negatives onto the same release print. More sophisticated techniques used optical printers or aerial image animation cameras, which enabled more exact positioning, and better interaction of actors and animated characters. Often, every frame of the live action film was traced by rotoscoping, so that the animator could add his drawing in the exact position.

With the rise of digital special effects, combining live-action and animation has become more common. The Star Wars prequels and the Lord of the Rings trilogy, for example, include substantial amounts of animation, though it may not be recognized as such because of the animation's realistic, non-cartoony appearance.
