James Gandolfini, who played the feisty but lovable Mafia boss Tony Romano in the hit HBO series The Sopranos, died of a heart attack on Wednesday, according to the entertainment site TMZ. He was 51.
Gandolfini was in Italy to attend a film festival in Sicily, reports said.
The Sopranos ran for six seasons until 2007. Critics hailed it as one of the greatest TV series of all time, winning 21 Emmys and five Golden Globes. Three of those Emmys belonged to Gandolfini.
