The British moviemaker is currently filming the latest installment in the 007 series in the U.K. with Daniel Craig and Dame Judi Dench, and he has taken time out to record a message for devotees.
The video shows the movie being made on the streets of London, with one scene filming outside Westminster Underground Station, and Mendes talking about why he took the project on.
He says, "The roots of me doing this Bond movie start way before anyone approached me, because I, like everyone else, have my own personal relationship with Bond which began when I was nine or 10 years old. So I've always been a fan of the movies...
"I was genuinely blown away by Casino Royale, I thought Martin Campbell did a brilliant job and also because of Daniel. I felt here was a man in a real situation again and it reminded me of how I felt when I watched the Sean Connery movies."
He adds, "Ironically I've never made an English movie. I've made six movies and this is the first time I've shot in this country. Which is an extraordinary thing. So I feel the American years were my apprenticeship for doing the Bond movie."
