RIGHT NOW they're filming in Montreal and I have a ton of set photos for you here. It's going to be 1940s Paris in the film, putting Benjamin at around age 40, so I don't think any of the cgi aging will be used here.
Here's a photo taken from soneone who lives in a building on the street where they're filming, so you get a great birds-eye view of everything. Semi-exclusive.
Here's some more semi-exclusive photos of extras on the set sent in my a reader, Oliver (thanks a lot by the way!)
Now, a huge collection of photos of Brad on set.
Let me know what you think of all the photos in the comments box on the side!
