Update:
Slashfilm has posted a written/video (NSFW) description of Kevin Smith's trip to Pinewood Studios.
Kevin Smith was recently invited to visit the
Episode VII set, and while he signed a non-disclosure agreement, and wasn't able to talk specifics, he did spill a few details. He said he saw costumes, characters, props, and sets that "took him back to his childhood", as well as a stage which had the Imperial Starship logo (with a sign that said ‘loose lips sink starships”) and nodded and smiled when asked if he saw any stormtroopers. " Dude, I cried four times. The seven year old in me came. [J.J] has [...] captured it, man. He has nailed it.”
