The tradition goes back all the way to the earliest days of animation with Winsor McCay's short Gertie the Dinosaur, which shows a live-action narrator (specifically, a "live" actor, instead of a filmed one) interacting with an animated landscape and character (Gertie). In one scene, the narrator appears to throw a real orange which is caught by Gertie (the real orange is replaced by an animated one just as it leaves the narrator's hand), and the film climaxes with a scene in which the narrator enters the animated landscape (again, replaced by an animated version) and takes a ride on the famous dinosaur's back.
In the later days of silent film, the popular animated cartoons of Max Fleischer included a series where his cartoon character Koko the Clown interacted with the live world; for example, having a boxing match with a live kitten. In a variation on this concept, Walt Disney's first directorial efforts (years before Mickey Mouse was born) were the animated Alice Comedies short cartoons, in which a young live-action girl named Alice interacted with animated cartoon characters.
In the era of sound film, the 1940 Warner Bros. cartoon You Ought to Be in Pictures, directed by Friz Freleng, can be seen as a predecessor to Roger Rabbit. The animated sequence in the 1945 film Anchors Aweigh in which Gene Kelly dances with an animated Jerry Mouse is one of the actor's most famous scenes.
The Disney Studio mixed live-action and animation in several notable films (which are primarily considered live-action):
- In The Three Caballeros (1945), Donald Duck cavorts with several Latin-American dancers, plus Aurora Miranda (sister of Carmen Miranda), who gives him a kiss.
- In Song of the South (1946), Uncle Remus sings "Zip-a-Dee-Doo-Dah" in an animated field, and tells the stories of Brer Rabbit through the animated sequences.
- So Dear to My Heart (1949) features sequences of a similar nature.
- Mary Poppins (1964) is one of the best-known films of this nature, including a scene in which Dick Van Dyke dances with cartoon penguins as Julie Andrews watches.
- Bedknobs and Broomsticks (1971) features a hybrid sequence in which Angela Lansbury and David Tomlinson dance together in an underwater nightclub, while Tomlinson must bear the brunt of aggressive, anthropomorphic soccer-playing animals in the latter half.
- Pete's Dragon (1977) does the opposite of its predecessors: it puts the animated dragon, Elliott, in a live-action setting.
There were also many previous films combining live action with stop motion animation using back projection, such as the films of Willis O'Brien and Ray Harryhausen.
Ralph Bakshi combined live-action and animation twice in 1973's Heavy Traffic and 1975's Coonskin (a.k.a. "Streetfight").
Who Framed Roger Rabbit (1988) broke new ground with its advanced special effects and "realistic" portrayal of the interaction of animated characters and live actors. With the commercial and technological success of Who Framed Roger Rabbit, a slew of live action/animated films followed, including Rock-A-Doodle, Cool World, Space Jam, The Adventures of Rocky and Bullwinkle, Monkeybone, Looney Tunes: Back in Action, The SpongeBob SquarePants Movie, Fat Albert, Charlotte's Web, and Enchanted.
The combination of live action and animation is very common in TV commercials, especially those promoting products appealing to children.
Techniques
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.
In the penguin sequence in Mary Poppins, they filmed the live action part first, having the actors sitting in front of a painted background. Then the penguins were added, probably by using cel overlay.
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.
