A ninth Harry Potter movie is secretly filmed, but fans of the films will have to visit the wizard's theme parks to see it.
46-year-old actress Helena Bonham Carter is among the cast members who have been shooting scenes at the studios in Hertfordshire.
'The cast have really enjoyed getting back together — they are so tight-knit,' a source told The Sun.
'The shooting schedule is nowhere near as long as the films, so though filming has been intense, the stars have enjoyed being able to pop in and out.'
The 'mini movie' will be showing at The Wizarding World of Harry Potter attraction in Florida, and two new Potter theme parks under construction.
The eight-part Harry Potter film franchise raked in a staggering £5 billion worldwide, making it the most successful movie series of all time.
