The Face of Boe is a fictional character in the British science fiction television series Doctor Who. Not portrayed on-screen by an actor, the Face of Boe is a wholly mechanical effect, resembling a gigantic human-like head with a weathered face and in place of hair, numerous tendrils which terminate in round pod-like structures. Typically this is encased in a clear sealed container and mounted on a movable pedestal base. The Face merely grunted during his appearance in "The End of the World", communicated telepathically in "New Earth" and "Gridlock", and spoke for the first and last time in the latter, and was voiced by Struan Rodger. It is stated in "New Earth" that he is thought to be millions of years old (billions, at least according to "Gridlock"), but responded to a statement of that with a leading question concerning the impossibility of such an age. It was suggested in "Last of the Time Lords" that the Face of Boe is a future Jack Harkness.
