It was an old-timey Western with a modern, real-life tragic ending. A crew member was shot and killed while filming the movie "Rust" in New Mexico. As we've covered here on The Newsworthy, actor Alec Baldwin fired the antique revolver that killed cinematographer Halyna Hutchins and injured director Joel Souza.

Authorities say an assistant director told Baldwin the gun was "cold," meaning it didn't have any live rounds in it, before he pulled the trigger. But that wasn't the case. Investigators now say they think the gun did in fact contain live ammunition. But they're still investigating and deciding who, if anyone, should face criminal charges.

To get a better idea of what may have gone wrong, and what should have happened, I'm talking with the president of the American Society of Cinematographers, Stephen Lighthill. He's also sharing his memories of Halyna Hutchins since she used to be his student at the American Film Institute.
