The highly-anticipated debut trailer for Star Wars: Episode VII is rumoured to be complete, with music yet to be recorded ahead of a release said to be "sooner than you might think".

A post on the John Williams Fan Network cited a source saying that the legendary composer is set to record new music next month having received a completed trailer from the film's director JJ Abrams.

"A reliable source just said [Williams] received a trailer from JJ Abrams on Monday, Oct 20," reads their article. "[Williams] has already written new Star Wars music to accompany this trailer. This new trailer will feature new music and will be recorded on November 15 in LA with full orchestra."

They also wonder whether Williams might record in London rather than LA, due to the toll a 14-hour flight might have on the 82-year-old.

This was followed up by Slash Film's Editor Peter Sciretta tweeting: "Re: Star Wars trailer - I have heard we will see it sooner than you might think."

One likely date for the trailer's release would be Thursday, 18 December, 2014, one year to the day from the film's scheduled release.

Star Wars: Episode VII stars John Boyega, Daisy Ridley, Adam Driver, Oscar Isaac, Lupita Nyong'o, Domhnall Gleeson, Andy Serkis, Max von Sydow, and Gwendoline Christie are opposite returning actors Mark Hamill, Harrson Ford, Carrie Fisher, Peter Mayhew, Kenny Baker, and Anthony Daniels.
