This video claims to be a behind the scenes look at Jane Got A Gun. Hopefully some time this year we might actually get some official marketing material, but this is most definitely not in that category. What it is are three photos. The first looks like a legit set shot (no Natalie), the second might be a still of Joel Edgerton in character but the quality is really bad (no Natalie), and the last image seems to be of an extra (no Natalie).

Thanks to Belerofonte.
