'Sin City: A Dame To Kill For' co-director has revealed Bruce Willis will return for the sequel and says Joseph Gordon-Levitt will portray a ''cocky gambler''.
Bruce Willis will return to 'Sin City'.
The Hollywood heavyweight is set to reprise his role as John Hartigan in 'Sin City: A Dame To Kill For', the sequel to 2005's dark thriller.
Meanwhile, the director dropped further hints about 'Inception' star Joseph Gordon-Levitt's new part in the film noir-inspired feature.
Robert said: ''It's a new character. He plays a gambler, a very cocky gambler, who comes in and tries to beat the biggest villain in Sin City at his own game.
''The story's called 'The Long, Bad Night'. He beats the wrong guy in a game and bad stuff happens to him.''
This news follows the announcement that 'Entourage' actor Jeremy Piven, 'Killer Joe' beauty Juno Temple and 'Goodfellas' star Ray Liotta have all joined the cast, which already includes Josh Brolin, Christopher Meloni and Dennis Haysbert.
Robert also revealed the gritty drama - set for release in October 2013 - would be tapping into 3D technology in an innovative way.
He explained: ''We're really playing with stuff because that's a very two-dimensional world and to see that stylisation in 3D, it'll blow people's minds. 3D hasn't been used like this yet.''
