Agh! What IS he known for, she wonders!! I've got nuthin'!
Oooh, Dev. I think we're past the 10 question mark and it's clue time.
Although fictitious names were used, a play, a 1960 movie and two TV movies, l988 and 1999, 'evolved' from an issue/event in which this man played a prominent part.
o.k. Stab in the dark here...While I do other research:
Christian Dior?
Not athlete
Not criminal
Not Christian Dior.
The movies all evolved from the play which evolved from the actual event. Lots of evolution there.
Sounds like Charles Darwin, but didn't someone already guess that?

Oh what can I say? How can I say it. I even said it wasn't Charles Darwin and Bree guess it right at the beginning. Will you ever forgive me?I'll quit. I promise. Yikes.
All is forgiven, and please don't quit, but -- from your hints, it almost sounded more like Clarence Darrow, and Inherit the Wind.
Ah, I'm a goner for sure. It is:
CLARENCE DARROW
And I'm sober, honest. I'll take a long rest and come back one day, senses restored, I hope.
It's all yours, Bree.
You're forgiven, aggie! No big deal. And please don't quit! I was going to guess the same thing, bree! Looks like it's your game. I've gotta go put kids to bed.
I've gotta go put myself to bed, so I'll pass, too. Dev, you did most of the leg work on this one, so feel free to start the next game when you come back.
I see nobody has stepped up to the plate, so I'll start the next round:
