The Sopranos creator David Chase has admitted that he found it "difficult" to end the show.
The acclaimed HBO gangster drama ended on a controversial note, leaving the fate of Tony Soprano (James Gandolfini) unresolved.
"It's just very difficult to end a series," Chase told The New York Times. "For example, Seinfeld, they ended it with them all going to jail.
"Now that's the ending we should have had. And they should have had ours, where it blacked out in a diner."
The Sopranos series finale 'Made in America' - which aired on June 10, 2007 - concluded with the screen fading to black for several seconds.
Series star Michael Imperioli (Christopher Moltisanti) later suggested that the last scene was intended to represent the death of the Tony Soprano character.
"I think he's dead," said the actor. "That's what happens when it goes black, right?"
Last month, Steven Van Zandt - who played mob enforcer Silvio Dante - claimed that a proposed Sopranos movie is unlikely to emerge.
"I don't think so," he said. "Just in case the movie does happen, Silvio will be there, but... it doesn't look likely, it really doesn't."
