There is a picture on paul amos' twitter account that show 5 actors involved in the game. It's seems coherent with what I read somewhere, apparently they ask the actors voicing the twins to hang around to develop real complicty in order to better retranscript that feeling into the game.

Paul Amos - Jacob Frye Jaz Deol - my bet is on Henry Green Victoria Atkins - my bet is on Evie Frye Samuel Crane - ? Gavin Fowler - ?
