I was getting in the mood and have started watching MacGyver again, starting with the first season from 1985/86.
And I love to see so many known guest actors in it:
Robin Curtis (Star Trek 3 & 4), Peter Jurassik (Babylon 5, Sliders), Nana Visitor (Star Trek DS9), Robert Englund (Nightmare on Elm Street, V), Stephen Williams (The Blues Brothers, 21 Jump Street), Teri Hatcher (Lois & Clark, Desperate Housewives), John de Lancie (Star Trek TNG, DS9, VOY, Stargate SG-1), …
