Avengers: Infinity War fell 56% on its second weekend, so Captain Marvel is not burning out quite so rapidly.
Despite the strong showing by Captain Marvel, cinema box office is 28% down on the equivalent weekend of 2018, which saw the arrival of Peter Rabbit and Tomb Raider.
US comedy What Men Want comes next in the UK lineup, debuting with a decent £817,000 from 495 cinemas (£837,000 including previews).
Reaching the £37m total of Captain America: Civil War is a realistic target.
