Despite the arrival of Glass and Mary Queen of Scots and solid numbers from Stan & Ollie, Mary Poppins Returns and The Favourite, overall box office is down 30% on the equivalent weekend a year ago.
Hence Glass, the new film from M Night Shyamalan, extending the story of his earlier films Unbreakable (2000) and Split (2017).
So far, Glass looks set to do just that, with a UK debut of £3.33m (£3.42m including previews).
In the US, Glass began with just over $40m, for which the UK equivalent would be £4m.
