For starters, this version of "Harvey" IS available on dvd, through the Film Collectors Society of America, which is how I obtained it. Picture & sound-quality much-better than I expected. Imagery slightly-faded but acceptably, adequately clear. Pretty-smooth production overall, considering it was performed live, if I understand correctly. I detected no moments of flubbed-lines, uncooperative-props, or clumsy camera-shots. Despite the eccentricities of various-characters, everyone acted naturally within the context of the premise. Watching Marion Lorne can be a trial at times, i.e., her patented confused & flustered portrayals, but she's very-good at it, actually conveying sympathy & affection for her by story's-end. Carney's excellent as Elwood P. Dowd, the fanciful-fellow who's convinced that Harvey's real--and very-nearly convinces others, including the director of the sanitarium! In terms of today, the comedy's a little-strained but remains likeable & pleasantly-amusing throughout. It's fun to see Elizabeth Montgomery in a pre-Bewitched role as the pretty-nurse, who comes to empathize & even a little-infatuated with the ever-gallant Elwood. Now that I've seen this version, I think I prefer Carney in the role of the rabbit-seeing eccentric, as opposed to Jimmy Stewart's version. Stewart inhabits & is very-effective as Elwood but he's such a familiar-actor that one finds this aspect somewhat difficult to get-past. Carney seems fresh & less-mannered or studied than Stewart. One detects the latter as "playing" an eccentric, whereas Carney is completely-natural & totally-believable, usually Stewart's strong-suit. The ending to the story is both sweet & touching, along with a magical-twist. In short, this Dupont Show of the Month from 1958 holds up well & definitely is worth-seeing. In modern movie-terms, I can see Tom Hanks in the role of Elwood, an actor always-capable of conveying likeability, believability, and sincerity. This is what "Harvey" is all about.
