Marvel's upcoming sequel Thor: The Dark World is set to start filming soon in England and the production office of 'another film' titled 'Thursday Mourning' put out a letter to the residents of the Bourne Wood area to let them know that they will be filming nearby in August and September. Though they don't actually say they're filming Thor, it's not hard to figure it out.

Portions of the letter read:

We are writing to let you know about some filming about to be undertaken in Bourne Wood in the coming months. Please find a brief overview and introduction to this project.

"Thursday Mourning" is the working title of a major feature film. It is comic book adaptation set in another "fictional realm".

We will be establishing a fictional village set in another realm, with yurts and village like dressing in the bowl. The sequence involves a battle between two kingdoms, ending in our comic book hero arriving to save the day. The sequence will involve a substantial amount of Stunts and controlled special effects all within the hours 0700 - 1900hrs. 

We plan to use most of the areas that are usually occupied by film units for all our support vehicles. The sequence will involve approximately 300 extras who will arrive in the early hours prior to call time to go through costume and makeup.

Sounds like a pretty epic battle scene in the making. Many movies have filmed in the Bourne Wood area. You can check out a list of the films by clicking here.

Thanks to 'Steve' for the heads up! Thor: The Dark World is set to hit theaters on November 8, 2013.
