Mamma Mia! reached £68m at the UK box office, and is currently the 11th biggest film of all time in the UK.
Last autumn, Goodbye Christopher Robin, which also tells the story of AA Milne’s son, reached £2.88m.
That film began with £776,000 from 324 cinemas in October 2005 on its way to a total of £3.61m.
Jason Statham and his giant prehistoric shark had a predictably short run at the top of the UK box office, with The Meg knocked off its perch by Ewan McGregor and his animal friends.
