Question: I would like to write about a real event in history in which some of the people involved are still alive today. Do I need to obtain a release from every living person in order to use their name in the story? Or do I not need to worry about this for a spec and leave that to the studio's legal team once my script is sold? Or.. would you simply advise me to change the names of all the characters and prelude the script with "based on true events"?
