Thanks to OLV, we have some additional photos taken at the Pratt Pullman Yard which is a filming location for The Hunger Games : Catching Fire.
Twitter user @racey_raee took the photos and wrote the following :
i think i saw haymitch. and i saw a bunch of extras in costume and i saw the tent for holding extras and the catering tent and i passed the row of trailers for actors. i didnt see anyone else. BUT STILL the big brown building with graffiti was where the main filming was happening. they had it blocked with all those semis.
