Talking about his role and the potential he saw in it, Farrell said: "I saw the part that I had, as quite obviously on the page was a father figure and somebody that was there to kind of corral and guide and care for and monitor these children as they go from birth into young adulthood. I loved it." 

Delving deeper into the character, Farrell gained a new perspective on his character's psyche. 

He said: "I think Richard (his character) is lonely, I mean he's got to be lonely. He's in space and he is again the only senior member of this team heading into the void. So, I think he has no one!" 

A big fan of the script, he shared how invested he was in first reading it: "It was a page-turner! It was really, really lovely. It was very unusual. I thought it was very cleverly drawn, and the questions that it provoked in me as a reader were fairly profound and substantial questions."
