In 2012, there were 647 films released in the UK, with 67 being thrillers. Thrillers made up 12 of the top 20 highest grossing films that year. The top 3 films were Skyfall, The Dark Knight Rises, and Marvel's Avengers Assemble. Skyfall was the most successful because it was highly anticipated and well marketed, including the promotion of its theme song. All three top films were part of established film series, allowing producers to make more money from viewers who enjoyed earlier installments wanting to see how the story continues. Thrillers made over $1.5 billion in profits that year. The target audience for these top films were young adults who were already fans of the series. However
