The latest instalment of the Planet of the Apes saga has topped the box office in the US and Canada for a second week running.
Dawn of the Planet of the Apes took $36m (£21m) in ticket sales in its second weekend.
The film has made almost $140m (£82m) in North America since its release, according the data company, Exhibitor Relations.
It held off competition from horror sequel, The Purge: Anarchy.
Dawn of the Planet of the Apes, a sequel to 2011's Rise of the Planet of the Apes - tells the story of the early stages of the survival clash between humans and apes.
Actor Andy Serkis has won critical acclaim for his motion-capture performance as the ape, Caesar.
The film also topped weekend sales worldwide, with an estimated $97m (£57m) ticket sales globally, according to the entertainment statistics company, Rentrak.
The Purge: Anarchy, the follow up to a 2013 summer hit, earned a solid £28m (£16.3m) in the second spot. The film cost just $9m (£5.2m) to produce.
In third place was Disney animation Planes: Fire & Rescue, the sequel to 2013's Planes, with takings of $18m (£10.5m).
Cameron Diaz and Jason Segel romping in the nude in the comedy Sex Tape was not enough to attract enough cinema goers to push the film into the top three. It charted at number four with takings of just $15m ($8.8m).
Transformers: Age of Extinction ranked second in world sales, but was pushed into fifth place.
The action film, starring Mark Wahlberg and a cast of shapeshifting robots, took $10m, bringing its US total to $227m (£133m).
"It was kind of a middling weekend unless you were the top film," said Paul Dergarabedian, senior media analyst for box-office tracker Rentrak.
Scrubs star Zach Braff's crowd-funded Wish I Was Here, which had a limited release on 68 screens, took just $495,000 (£290,000).
Its earnings are expected to fall far short of his directorial debut Garden State in 2004, which earned $26.8m (£15.7m).
