Movie based on a play

Thinking about "The Best Man" (1964) starring Henry Fonda, made me think of other movies based upon plays, and also the interesting differences between the art forms.

A movie -- you can do over and edit, to get it right, then you have one finished product.
A book, also -- it's about the finished product, which people then buy and read.

A play -- you attend it. And while it's supposed to be the same every night, the process of ironing out differences and difficulties and tough patches may continue.

Is a play like a blog? If you were writing the same blog every day, and trying to make it better, but essentially discussing the same info & ideas.

Movies based on plays: I guess there may have been many, many. (Were all of the Rodgers & Hammerstein musical movies first produced for the stage? The Sound Of Music; Oklahoma!; South Pacific? Yeah, I think so.)

Then -- "Hello, Dolly!"; "Chicago"; and "The Best Man," the political play we discussed Saturday.

Oh, and "Play It again Sam" -- Woody Allen's very funny film predecessor to his '70s Major Treats, "Annie Hall" and "Manhattan" -- "Play - Sam" was a play, first.

When I think of what actors go through, to put on a play -- the repetition -- the idea of it blows my mind. The physical and mental involvement with the material night after night, with the audience right there. It would have to be a whole different experience from filming -- not to say better or worse, just different.

Plays I've seen: "Bring In Da Noise, Bring In Da Funk": Broadway, New York, New York.
"The King And I" Boston
"Fiddler On The Roof" -- college production.
And more. Those are main ones.
