The cast was assembled in Detroit last week, and now we know why! Camera tests and a wee bit of filming!
Diana Lane, Martha Kent in Batman vs Superman, commented on what’s been going on in Detroit.
"Lane also plays a mom in the upcoming Batman-Superman film, reprising her Man of Steel role as Martha Kent. The actress told THR that she just came back from Detroit, where they’re doing camera tests for the highly-anticipated sequel. She said that she filmed a few shots of her feeling the Superman costume and joked that she hadn’t had the chance to do the same with the Batman costume."
