George Pan Cosmatos (4 January 1941 – 19 April 2005) was a Greek-Italian film director and screenwriter. Following early success in his home country with drama films such as Massacre in Rome with Richard Burton (based on the real-life Ardeatine massacre), Cosmatos retooled his career towards mainstream "blockbuster" action and adventure films, including The Cassandra Crossing and Escape to Athena, both of which were British-Italian co-productions. After relocating to North America, he directed the horror film Of Unknown Origin. This was followed by some of his best-known work, including the action films Rambo: First Blood Part II and Cobra (both of which star Sylvester Stallone), the science-fiction horror film Leviathan, and the critically acclaimed Western movie Tombstone.
