Mick Fleetwood

Actor (Antedean dignitary) — The Next Generation

British drummer and co-founder of Fleetwood Mac who made a cameo under full fish-like make-up as an Antedean dignitary in the Next Generation episode Manhunt.

Mick Fleetwood is a British musician, the drummer and co-founder of the rock band Fleetwood Mac. A fan of Star Trek, he asked to appear in The Next Generation.
He was cast in the second-season episode Manhunt as one of two Antedean delegates carried to a conference on Pacifica. The Antedeans are fish-like beings who travel in a trance and then eat voraciously on waking, and the role left Fleetwood unrecognisable beneath a full head mask.
At the end of the episode Lwaxana Troi reads the pair's thoughts and exposes them as assassins carrying explosives. Fleetwood has also taken occasional acting roles elsewhere, including the film The Running Man.
