Blockbuster is a movie game for anyone who has seen a movie, and like all the best films it comes in two parts:
In the Movie Buzzer Battle, both teams are given a topic, such as "Movies with dogs". You start the 15-second timer, yell out a relevant movie, then whack the buzzer to reset the time. The other team is now in the hot seat and has to do the same. Whoever runs out of time hands the advantage to the other team, which takes control of the next round: Triple Charades Jeopardy.
In this round, teams have to guess the movie, while you act it, use one word, or quote from it. There is all sorts of strategy and stealing, too.
