The first rule of Star Wars: Episode VII is, you do not talk about Star Wars: Episode VII.

Film producer Frank Marshall, who is married to Lucasfilm president Kathleen Kennedy, posted a Twitter pic Monday of a poster from the Pinewood Studios set in England.

The poster, featuring the words "Loose Lips Bring Down Starships," shows an Imperial commander getting choked by Darth Vader's hand. Clearly, sharing set spoilers is not encouraged.

"Excited to be here at Pinewood, but mum's the word..." Marshall captioned the photo.

The poster appears to be similar to the artwork director Kevin Smith described when discussing his set visit in July. Smith said he told director J.J. Abrams' assistant that he loved the poster, to which the assistant responded: "J.J. hung that up for you."

Very little is known about the ongoing shoot, and Smith couldn't reveal much, having signed a nondisclosure agreement. But he did divulge that the scenes felt "tactile," rather than relying on lots of green screens and CG images. Smith added the experience left him with tears of joy.

See Marshall's pic below, as noted by Yahoo Movies.
