All of the top grossing films of 2016 were produced by the big six production companies. Also, 4/5 of these movies were released in either the summer or winter- very close to the school holidays, if not in them. All of these films were also aimed at families and the younger audiences so it makes sense for them to come out when there are lots of young people available to watch them.
As well as this, three of the films were sequels (Finding Dory, Captain America, Star Wars) and one of these films was a remake of an already well known and loved film- The Jungle Book. Therefore, these films would have already have a mass following and so it is understandable that they were part of the top five grossing films. They already had many fans and were highly anticipated; Finding Dory was announced years before it was released and so had many people looking forward to seeing it in the cinema.
