Arnold Schwarzenegger’s page in Hollywood history will not talk about art. It will explain his contribution to the genre known as summertime blockbuster action films. “Eraser” (1996) might get mentioned because it’s a perfect example. Arnold must protect a federal witness (Vanessa Williams) from the four horsemen of action movies: pyrotechnics, technology, organized crime and double-crossing government officials. There’s beauty, humor, helicopters and explosions. The climax is just as implausible as the rest of the film and don’t ask me about Arnold’s accent. Just eat your popcorn and enjoy the air conditioning for two hours. It’s hot as hell outside.
