Oscar-winning composer Hans Zimmer dedicated a performance of his The Dark Knight theme tune to the movie's late star Heath Ledger.

The German musician played a concert in London on Friday (10Oct14), reviving his iconic movie music with a live orchestra, and he took the opportunity to honour Ledger, who played The Joker in the 2008 Batman blockbuster but died before it was released.

Zimmer dedicated The Dark Knight music to the late actor, telling the audience, "When Heath died I thought I should make the score simpler but then I knew he would have wanted the edge kept in it."

The composer was joined on stage by rocker Johnny Marr, his collaborator on The Amazing Spiderman 2 soundtrack, and Happy hitmaker Pharrell Williams at his second gig at London's Hammersmith Apollo on Saturday night (11Oct14).
