Peter Jackson used Facebook to release Ed Sheeran's new song that will play during the closing credits of The Hobbit: The Desolation of Smaug.

Sheeran teased the song, "I See Fire," to his 8 million Twitter followers on Monday before Jackson unveiled the making-of video on Facebook a day later

"It's always tricky to think of the right person to create and [perform] these songs," Jackson wrote, giving his daughter credit for roping in Sheeran. "Someone who shares our passion for Tolkien, and somebody who is prepared to respect the film."

The sequel, which is a follow-up to 2012's An Unexpected Journey, hits theaters on Dec. 13. The film follows Bilbo Baggins, Gandalf and the 13 dwarves, as they continue their journey to reclaim dwarf kingdom Erebor from the fire-breathing dragon Smaug.
