Sam Smith to sing theme of next James Bond movie

Grammy-winning British vocalist Sam Smith has been confirmed as co-writer and performer of the theme song of upcoming James Bond film "Spectre."

The song "Writing's On The Wall" will be released on Sept. 25, a month ahead of the movie's theatrical debut on Oct. 26 in the. U.K. The North American release of "Spectre" is set for Nov. 6.

The announcement by distributor Sony Pictures Entertainment came only a day after Smith dropped a heavy hint on social media. He posted on Twitter and Instagam accounts a photo of him wearing a "Spectre" ring.

"Sam and Jimmy Napes have written the most inspirational song for 'Spectre' and with Sam's extraordinary vocal performance, 'Writing's On The Wall' will surely be considered one of the greatest Bond songs of all time," said producers Michael G. Wilson and Barbara Broccoli, in a statement.

"This is one of the highlights of my career. I am honoured to finally announce that I will be singing the next Bond theme song. I am so excited to be a part of this iconic British legacy," said Smith.

As befits the usual cloak of secrecy surrounding the Bond series, Smith on several previous occasions had denied that he was doing the "Spectre" song. "That's not me," he told BBC Radio 2.
