The actor gets a movie name in secret and acts it out without speaking or mouthing words.
Their team guesses within the time limit, usually 60 to 120 seconds.
A correct guess scores points. Then the next team's actor goes.
A worked example
Say the movie is Chak De! India. Crank the camera (film), hold up three fingers (three words), then two fingers (second word). Tug your ear for "sounds like" and act "day" by pointing at the sun. Once someone says "De", act "India" with a cricket chant and they will have it.
