Sigourney Weaver is in negotiations to star in the sequel to new fantasy film The Mortal Instruments.
The Mortal Instruments: City Of Bones, starring Lily Collins, Jamie Campbell Bower, Kevin Zegers, Robert Sheehan, Jemima West and Jonathan Rhys Meyers is due out in cinemas in August. But work has already begun on a sequel The Mortal Instruments: City Of Ashes.
The film is based on the teen fantasy romance books by Cassandra Clare. Set in Victorian England, they feature a girl who finds out she is part of a hidden race of demon-slaying angels known as Shadowhunters locked in a battle with warlocks, vampires and werewolves.
Alien star Sigourney is in talks to play the ruthless leader of the Shadowhunters who will stop at nothing to destroy the man who killed her son.
Most of the cast from the first film are returning for the sequel, and shooting is currently scheduled to begin in October.
