This is an enjoyable activity which introduces some film and storytelling vocabulary while practicing use of the present simple in talking about films and books.
Write some present simple sentences describing the plot and setting of a well known film, for example:
It’s set on a big ship
It takes place in the early 1900s
It’s about a rich girl and a poor boy who fall in love
Unfortunately, the ship sinks and the boy dies
At the end, the girl, who is now an old lady, revisits the scene of the tragedy
Students try to guess the film (not too difficult) and then in pairs or alone write some similar sentences to describe their own choice of book or film. The class then tries to guess each other’s choices.
