Moore: Cavill killing himself actually came from
Dean Stockwell [the actor who played Cavill]. As scripted in that final climatic
CIC battle, Tigh was going to grab Cavill and fling him over the edge of the upper level and he was going to fall to his death. Dean called me and said “y’know, I just really think that, in that moment, Cavill would realize the jig is up and it’s all hopeless, and he should just put a gun in his mouth and shoot himself.” And I said: “…Okay!”
