In The X-Files, the Cigarette Smoking Man (played by William B. Davis) only smokes Morley cigarettes. Rarely scene without a cigarette in his hand, the CSM was originally intended to be a non-speaking character always lurking in the shadows, but he was eventually given dialogue and became the show's primary antagonist. In "Two Fathers" (Episode #126), his name was finally revealed to be C.G.B. Spender, and in several episodes it is strongly suggested that he is Fox Mulder's biological father.
