In September 2025, the production closed St Bartholomew the Great – the Norman priory church in Smithfield, founded in 1123 and one of the oldest and best-preserved medieval interiors in London – to the public from September 9, with a scheduled reopening on September 18. St Bartholomew the Great has appeared in Four Weddings and a Funeral, Shakespeare in Love and The Other Boleyn Girl. Its interior is so authentically ancient that it requires no dressing for period productions.
In January 2026 – the final weeks of the shoot – filming moved to the Old Royal Naval College in Greenwich, the Baroque complex designed by Christopher Wren, transformed into 1955 London.
From August 26 to 30, the production filmed at Victoria Baths in Manchester – a Grade II* listed Edwardian swimming complex in Chorlton-on-Medlock. A casting call sought 40 boys aged 11 to 14 for a bath sequence, with short neat hair for the 1950s setting, suggesting a boarding school scene.
Bradford followed Manchester as the production's next Northern England location, with filming taking place in Little Germany – the area known for its imposing Victorian warehouse architecture – and at Lister Mills, a large former silk factory. Filming was also confirmed on Cater Street, Currer Street, and Bolton Road/Stott Hill. Bradford residents filmed Jadis on horseback in their streets – one TikTok video was captioned "Narnia filmed in my back garden."
The film premieres in cinemas on November 26, 2026, with a Netflix streaming debut on April 2, 2027.
