Irene was downgraded from a hurricane to a tropical storm Sunday, but the weekend already was a lost cause for many theaters in its path.
Late August often is a dumping ground for movies with slim commercial prospects, and Irene cut even further into receipts for the weekend's three new wide releases.
Zoe Saldana's action tale "Colombiana" opened in second-place with $10.3 million. Guy Pearce and Katie Holmes' horror story "Don't Be Afraid of the Dark" debuted in third with $8.7 million. Paul Rudd's comedy "Our Idiot Brother" premiered at No. 5 with $6.6 million.
