The X-Men star will give tours of London locations featured in his 1995 film Richard III.

"I've always thought it might be fun to take a bus tour around the sites of Richard III," he says. "You would watch snippets of the film sitting in the coach and then arrive at the actual location and see it."

The bus tour will be part of the BFI Presents Shakespeare on Film project, which will run throughout April and May (16).

In addition to the bus tours, MCKellen will also be on hand for an onstage discussion with the movie's director, Richard Loncraine, following a screening of the film. He will also take part in a Shakespeare-based variety show, organised by the BBC and The Royal Shakespeare Company, alongside Dame Judi Dench, Joseph Fiennes and David Tennant.
