I worked on a major motion picture movie set a few years ago. I was not asked to sign a non didclosure agreement. Recently the movie was released and has become a huge box office hit. I was given permission to take camera still photos during filming. Some of my pictures were of the movie stars doing funny and crazy things. Some of the pictures were of artwork that was produced only for the movie then later destroyed. I now want to sell my images as framed fine art on the internet. Can I legally do that???
