Jean LaFitte Two-Part Epsiode
I remember one of the most interesitng segments of "Swiss Family Robinson" was a two-part segment starring a young Frank Langella (even pre-'Dracula') as the legendary Pirate, Jean LaFitte.
It had alot of swash-buckling action, and a solid adventurous storyline. They should have done more like that, but I guess the budget wouldn't allow from the production to get too 'crazy' with the action.
I seem to recall that this two-parter was planned as a spin-off from SFR.
