That's Doctor Zaius from the first two films, Minister Of Science and Chief Defender Of The Faith, played by Maurice Evans; and Councillor Zaius from the TV series, politician, played by Booth Colman. They are not supposed to be the same character (contrary to some opinions, for some unfathomable reason).
re the caption on this. No. Just no.
A third Zaius appeared in the animated series too. Confused? You should be.
