Just wondering about the copyright aspects of using some footage of a TV show or movie for the purposes of a review. As an example, my daughter is 10 and wants to review the new Ninja go movie. Can we use any footage, say from the trailer so her references make more sense? Same with Nickolodeon TV shows? Though I don't know if any trailers would be available, I might have to use real footage? Sorry if this has been covered before.
