In-Camera and Compositing Tricks
Using effects such as reverse motion, split performances or live action mixed with animation to place impossible things in one frame. The trick is part of the show.
Bad Taste
Jackson plays both Derek and the alien Robert. The cliff fight uses shots filmed months apart, but careful editing makes it look like the two are fighting each other.
Who Framed Roger Rabbit
Cartoon characters cast shadows, hold real props and move with the live camera. On set, puppeteers, rubber mannequins and robotic arms helped the actors react to something. Because the animation sits so firmly in the frame, you believe it.
