A Salvador Dalí masterpiece was finished more than half a century after he started it - not out of reverence for the surrealist artist but to secure ownership of a priceless archive of his work, a nephew of Walt Disney revealed yesterday.

Dalí's animation, Destino, begun in 1946 and completed in 2003, has its British premiere this week at the first exhibition devoted to the artist's fascination with film, at Tate Modern until September 9.
