This trend of content internationalization shows no signs of abating. While the drama of Argo and the humor of Ted cost less to produce, they are risky in international markets. Franchise films, with known characters, made in 3D and laden with special effects present the least content risk internationally. Yet these films carry their own risk due to large budgets. The special effects alone for a major film may exceed $100 million. The Avengers, The Dark Knight Rises, and Sky fall all rank in the top 10 for worldwide gross. Combined, they constitute an investment of
$670 million in production costs.
