The actor said that he hoped audiences would appreciate his alter ego Martin Bohm's constant struggle to connect with his mute son Jake (David Mazouz).

"There are underlying consistencies [between Touch and 24]," he told the Radio Times. "In the same way Jack was confronted by insurmountable odds, Martin is never going to have the typical, idyllic relationship that a father and a son hope to have.
"Yet he still fights to have a better relationship with his son, so both characters have courage even though it's utilised in different ways."
On what drew him to Touch, Sutherland added: "When I read the script, I found it fascinating, unbelievable, hopeful - the idea that what seems to us to be an insignificant moment can have a profound effect on someone else.
"The whole concept of connectivity made me feel a stronger sense of responsibility in how I am in my life."
Touch, which comes from Heroes creator Tim Kring, airs Tuesdays on Sky1 in the UK and returns to Fox in the US tomorrow (March 22).
