Filming has now started at the University of Pennsylvania and you can be sure reports and pictures galore shall start pouring in shortly, much as they did in Bethlehem, PA.

First up, a local website, “Dueling Tampons” (I don’t know – best not to ask), managed to capture a shot of Shia LaBoeuf up close and personal, sporting a green “recycling” t-shirt:

TLAMB and FadeSilverScreen have both posted pictures from filming yesterday (at the Quad) and today (at the Castle). One set of images comes via BP, showing the setup at UPENN, stating that filming at the Quad lasted most of the day – almost exclusively with Shia LaBoeuf, though it has also been confirmed that Kevin Dunn (Sam Witwicky’s dad) was on set – as pictures from FadedSilverScreen reveal. Images from today show Shia dressed in blue as he strolls past the camera as shooting begins at The Castle. Michael Bay shows up at the end to greet and sign HD-DVDs for waiting fans.
