The Warner Bros. animated film “Tom and Jerry” shocked the industry this weekend by making $13.7 million at the domestic box office. The biggest three-day opening for a movie since theaters partially reopened across the country last summer. No other film this weekend came close to “Tom and Jerry” totals. “The Croods: A New Age” came in at second place with a paltry $1.2 million., “The Little Things” nabbed $925,000, and “Wonder Woman 1984” pulled in $710,000 for fourth place.
