Two films that just opened came to life at the box office over the weekend, while another new release was pronounced DOA. The Sigourney Weaver/Jennifer Love Hewitt comedy Heartbreakers — featuring the actresses as a mother-daughter team of con artists — debuted at No. 1 with a respectable $12.3 million gross. The African-American relationship dramedy The Brothers took second place with $10.7 million. Rounding out the top five were the Steven Seagal/DMX action flick Exit Wounds (dropping from No. 1 to No. 3 with $9.2 million), Enemy at the Gates (No. 4 with $8.4 million) and Oscar winner Crouching Tiger, Hidden Dragon (No. 5 with $4.7 million). At the same time, everyone associated with the dismally reviewed Chris Klein/Heather Graham incest debacle Say It Isn't So no doubt was saying exactly that when the weekend returns came in: The pic entered the chart at No. 10 with a pathetic $3.1 million.
