groucho marx!!! gene wilder!

[macabre]

hi
I am well aware that allhallowsday is a massive fan of gene wilder.I am a massive fan of the Marx brothers.My question is this:do any of you guys know of a documentary that was made by an American TV station that had various comedians,dick van Dyke,don knotts and i believe gene wilder talking about how groucho Marx influenced them? I would be very keen to own this programme should it exist.
macabre..
