Shooting has official started for season 4 of Falling Skies, which, for fans, means the beginning of a steady trickle of spoilers and behind the scenes photos.

As the TNT sci-fi machine grinds back into gear in Vancouver, the official Falling Skies Tumblr has released the title of next summer's premiere episode - "Ghost in the Machine."

Set only two weeks after the conclusion of "Brazil," "Ghost in the Machine" will depict the 2 nd Mass on the move once more, according to recent pictures.

"A sneak pic from the season opener. Don't tell anyone... ;)," tweeted Drew Roy (Hal Mason), along with a photo of the resistance soldiers traveling across a field in a long column.

If you look closely at the new pic, you may see a figure leading the way that seems to bare a striking resemblance to Captain Weaver (Will Patton).

Another photo uploaded by Sarah Carter (Maggie) shows Lourdes (Seychelle Gabriel) - sans chains - and the rapidly growing "baby" Lexi. Pope (Colin Cunningham) and Lyle (Brad Kelly) have also returned to cause trouble with their Berserkers.

It remains unclear as to whether or not the group will be settling back down in Charleston when the series resumes. As the season finale wrapped up, Weaver commented on how it looked like things would be getting back to "old times" while Tom (Noah Wyle) had stated that the new capital may not accept his new half-human/half-alien child.

Falling Skies will return to TNT next summer. In the meantime, check back here for the latest updates.
