The excitement is building for the release of the next installment of James Bond.

You won't see him on the big screen but you will hear Sam Smith in Spectre.

British singing sensation Smith has tweeted that singing the theme song for the film is "one of the highlights of my career."  He wrote the song in 20 minutes after reading the script.

It was last week that Smith denied any part in the new Bond movie.

Spectre, starring Daniel Craig as James Bond opens in theaters in October.
