 I'm Paul Henley with NewsHour, live from the BBC. The Hollywood actor Alec Baldwin has appeared in court today accused of involuntary manslaughter following a deadly shooting on a film set. The cinematographer Helena Hutchins was killed by a bullet fired from a gun Alec Baldwin was using in a scene filmed in New Mexico. He's pleaded not guilty, saying other crew members had told him the gun was safe and that the weapon went off without him pulling the trigger. Emma Vardy reports.
