Below you can read some spoilers and take a look at set photos for Supernatural season 6 episode 11, titled "Appointment In Samarra". Thanks to Canada Graphs.
- Filming of variety of scenes that had Jensen Ackles (Dean Winchester) & Lindsey McKeon (Tessa) walking down two different sides of the street exchanging dialogue. You can see photos below,dialogue unknown.
- After they finished exteriors they went inside a store to film more scenes, and were still there till light outside was pretty much gone for shooting anything of Jensen walking back or forth.
- Once they wrapped in the store, they moved across the street to an abandoned warehouse. It was now dark, I was across the street and the compound was all gated in with the trailers inside the compound...
- Jared wasnt' seen on the set. Perhaps he was in the warehouse scenes at some point?
Update: new photos from Nigel Horsley added.
