Lord of the Rings fans have praised a decision to bring back Christopher Lee as Saruman by using archive footage rather than artificial intelligence.
Lee died in 2015, aged 93, having played Saruman in five different Lord of the Rings films. from The Fellowship of the Ring in 2001 to The Hobbit: The Battle of the Five Armies in 2014, which was the last film he starred in to be released during his lifetime.
