The remake of fantasy epic Clash of the Titans has made its debut at number one in the UK and Ireland and box office.
The film, which was made using 3D technology, took £5.6m and beat 3D animation How To Train Your Dragon with takings of £4.8m into second place.
Superhero movie Kick-Ass rounded out a brand new top three over the Easter weekend with returns of £3.8m.
British romantic drama Remember Me, starring Twilight heart-throb Robert Pattinson, was a new entry at seven.
