We spotted Jennifer Aniston on set today as she was resting between takes of her latest project, Marley and Me.  Also on hand was a prop dog who was used in a pet burial scene.  Speaking of which, is that thing left over from the set of Pet Semetery, because it’s kind of frightening!  Thankfully the living, breathing Marley is a very adorable golden lab ala Comet from Full House.
