This play was previously filmed and released with Gabe Kaplan in the title role. Having seen both versions I can state unequivocally that I prefer the earlier version. Gabe Kaplan (of TVs "Welcome Back, Kotter" fame), was someone who actually knew Groucho during his life and it showed in his comic timing, mannerisms, and facial expressions. Ferrante's voice was unappealing, his characterization came off at times as being smug, and he simply did not have the physical agility that Groucho himself had even into his 50's (see the Marx's "the Big Store" for proof). Sadly, the original version (which was entitled simply "Groucho") is no longer in print, but if you can track down a copy on ebay I would suggest that as a better purchase.
