Filming at Eastern State Penitentiary, Philadelphia? June 6th, 2008, posted by FofR

Slash Film have reported, via Jason X, that TF2 producers were scouting locations with scale models of Optimus Prime, Megatron and Star Scream:

My girlfriend works at Eastern State Penitentiary in the Fairmount area of Philadelphia. It was used as a prison from 1829 until 1971, and is now a historical site and museum. Anyway, at the prison today producers for Transformers 2 were on site with scale models of Megatron, Optimus Prime and Star Scream and were scouting filming locations in cell block 1 and the prison kitchen. Just thought I’d let people know that filming should begin here soon.
