At least that is what the Londonist is saying:

And, cos this is London, and our Film Festival rocks, director Ron Howard will also be watching, along with cast-members Frank Langella, Michael Sheen, Kevin Bacon, Oliver Platt, Toby Jones, Matthew Macfadyen, and (fanfare) the subject of the film, Sir David Frost!

That's just some of the celebs that are going to be hanging out in our amazing city over the next few weeks. (Think Eva Green, Gwynnie, Liam Neeson, Colin Firth and more.)

Thanks JaneV, for the heads up!
