Amy Schumer, Julianne Moore and Mark Ruffalo have joined more than 200 US actors, directors, producers and writers in signing an open letter calling for a change to gun portrayal in Hollywood films and TV shows.This year has already seen over 250 mass shootings in the US, with recent events in Buffalo and Uvalde provoking further debate in a country where more than 40,000 people are shot and killed with guns every year.The newly published letter from the Brady Center To Prevent Gun Violence – also signed by Shonda Rhimes, J.J. Abrams, Kathleen Kennedy, Judd Apatow, and Jimmy Kimmel, among others – attributes the problem to “lax gun laws” and politicians “more afraid of losing power than saving lives”, but notes that representations in film and TV can play a part.It's up to us to make sure senators #DontLookAway from our country's gun violence crisis.
