Children's film ideas

We will be doing a live action film, and we have watched some past students work as well as more famous ones, overall we came to the decision that doing an animation would be very long process in a limited time period. For the actual content of the film we liked the idea of a small person in a big world, and the idea of being able to do something extraordinary such as time travel. Overall we are still not sure what we will do when it comes to the content of the film.
