Jamie Foxx has admitted he believes movies influence real life violence.
The 'Django Unchained' actor said Hollywood could not ignore that it is partially responsible for inspiring the people behind such attacks.
Foxx is one of approximately 50 celebrities who banded together in a new US ad campaign demanding a plan against gun attacks following the recent Sandy Hook Elementary School massacre in Newtown, Connecticut, in which 20 children and six adults were killed.
The 45-year-old Oscar winner, who has an 18-year-old daughter Corinne, said: "We cannot turn our back and say that violence in films or anything that we do doesn't have a sort of influence. It does."
Jamie's comments come just one day after a new public service announcement, featuring him and dozens of other celebrities such as Beyonce, Selena Gomez, Jennifer Aniston, Michelle Williams, Steve Carell, Reese Witherspoon, Jennifer Garner, Gwyneth Paltrow, Cameron Diaz, 'Mad Men' star Jon Hamm, comedian Will Ferrell and Jason Bateman was released demanding a plan to end gun related atrocities.
However, acclaimed director Quentin Tarantino, whose is the man behind violent blockbusters including 'Pulp Fiction' and the 'Kill Bill' volumes, said he was tired of defending his films when there was another gun attack and "tragedies happen". He said the blame should only fall on the perpetrators.
