The pair were busy at work on their new film I’m.Mortal which costars Amanda Seyfried, Mad Men star Vincent Kartheiser, Cillian Murphy, and Johnny Galecki. The sci fi flick, set to be released in 2012, takes place in the not to distant future where the aging gene has been shut off.

It sounds like this is sure to be one very interesting film!
