'The Sopranos' comes to an end in US
Three different endings were filmed in a successful effort by creator David Chase to stop the outcome from being leaked.
James Gandolfini, who plays Tony Soprano, and the rest of the cast attended a party and special screening of the episode Florida's Hard Rock Hotel and Casino.
But the episode itself, which did not kill off the Mafia boss as some had expected, technically leaves the way open for a comeback.
Channel 4 will air the final episode in the UK in the autumn.
