Seyfried lands sci-fi film 'I'm.mortal'

Amanda Seyfried will lead the cast of sci-fi action movie I'm.mortal, reports Variety.

The project, from Gattaca writer-director Andrew Niccol, centres on a society where ageing stops at 25 and those wishing to live longer must buy and bank extra time to continue their life.

Seyfried will play a rich hostage who goes on the run with a rebel from the ghetto after he is accused of murdering someone to steal their time.

Niccol admitted that finding actors in their mid-twenties for every role has resulted in "a strange casting process".

He said: "Even for a small role like a priest or a pawnbroker, where you would normally cast a 75-year-old character actor, I have to find a 75-year-old character actor in a 25-year old body."

Niccol's other directing credits include S1m0ne and Lord Of War. The New Zealand-born filmmaker also had a hand in the scripts for Peter Weir's The Truman Show and Steven Spielberg's The Terminal.
