(New York, NY) -- There's another development from the October movie set shooting in New Mexico.  

Actor Alec Baldwin insists he didn't pull the trigger on a prop gun he was holding during rehearsal for the Western "Rust." He claims someone put a live bullet in it, which killed the cinematographer and injured the director.  

This is Baldwin's first sit-down interview since that day. It airs tonight in an ABC News special and will stream on Hulu shortly after.
