Schwarzenegger's commercial peak was his return as the title character in 1991's Terminator 2: Judgment Day, which was the highest-grossing film of 1991. In 1993, the National Association of Theatre Owners named him the "International Star of the Decade". His next film project, the 1993 self-aware action comedy spoof Last Action Hero, was released opposite Jurassic Park, and did not do well at the box office. His next film, the comedy drama True Lies (1994), was a popular spy film, and saw Schwarzenegger reunited with James Cameron.
