Yes, it's Jennifer Aniston and Owen Wilson filming some movie (presumably about a dog who plays baseball called Air Bud Selig...zing!) at Dolphin Stadium née Pro Player Park née Joe Robbie Stadium (that's where the Marlins play). Color me unsurprised that the backdrop of this movie shows the Reds losing. OMIGOD I AM ON FIRE TODAY JUST LIKE MICHAEL MUSTO!
Update: Thanks to the super-awesome Meech from Bugs & Cranks, there is video evidence.
