SCOTTISH actor Ewan McGregor is starring in a film based on a true story about a Spanish family affected by Thailand’s tsunami eight years ago.

The Impossible tells the story of Maria and Henry, a young couple who were in their hotel pool when the disaster struck in 2004.

“The real family is Spanish, but we play them as Brits,” said McGregor.

The film, produced by Spanish director Juan Antonio Bayona, was filmed in both Alicante and Thailand.
