Christopher Nolan's mindbending Tenet made it eight weeks on top of the box office in the UK and Ireland over the weekend, according to final figures.
Amid a backdrop of cinema closures and a reduction in opening hours due to coronavirus, the film added £187,275 to put it within a whisker of reaching a total of £17 million.
Second place went to concert film Michael Ball & Alfie Boe – Back Together, which drew in £175,778, followed by the supernatural thriller Saint Maud in third with £132,282.
I Am Greta, a documentary about climate change activist Greta Thunberg, pulled in a very modest £29,687, which was still good enough to open in eighth place.
This Friday - the start of the half-term holiday - will see the release of Sky Cinema's The Secret Garden and the family-friendly Max Winslow and the House of Secrets.
