Word is that Tony will show up in this using footage that was cut from Civil War.
Tony Stark was my favorite part of the MCU, but since they're making stories that fall between the existing movies, I'm hopefully he'll eventually show up. That's really what is keeping me interested until the X-Men show up.
Robert Downey Jr isn't dead. Why are they using cut footage?
He gets paid for appearing in a movie, not for appearing on set.
Not if his Civil War contract says they can use any of the footage in other MCU films and trailers, which I would imagine it does. I think most the time once you have the footage, the studio owns it to do what they want with it.
