Benigni is widely known outside Italy for his 1997 tragicomedy Life Is Beautiful (La vita è bella), filmed in Arezzo, also written by Cerami. The film is about an Italian Jewish man who tries to protect his son's innocence during his internment at a Nazi concentration camp, by telling him that the Holocaust is an elaborate game and he must adhere very carefully to the rules to win. Benigni's father had spent three years in a concentration camp in Bergen-Belsen, and La vita è bella is based in part on his father's experiences. Benigni was also inspired by the story of Holocaust survivor Rubino Romeo Salmonì. Although the story and presentation of the film had been discussed during production with different Jewish groups to limit the offence it might cause, the film was attacked by some critics, who accused it of presenting the Holocaust without much suffering, while others argued that a comedy about such a subject was not appropriate. More favourable critics praised Benigni's artistic daring and skill to create a sensitive comedy involving Holocaust, a challenge that Charlie Chaplin confessed he would not have taken on with The Great Dictator had he been aware of the true horrors occurring in ghettos and concentration camps in Europe at the time.
