Neil Simon plays - autobiographical or not?

Barefoot in the Park (1963)* - yes, based on his first marriage
The Odd Couple (1965)* - kind of, based on his brother and mate
Sweet Charity (1966) - no, musical adaptation
The Star-Spangled Girl (1966) - no, Simon regretted not doing concept justice
Plaza Suite (1968) - no, just funny
Promises, Promises (1968) - no, musical adaptation
Last of the Red Hot Lovers (1969) - no, just funny
The Gingerbread Lady (1970) - no, based on people he roughly knew
The Prisoner of Second Avenue (1971) - no
The Sunshine Boys (1972) - no, based on old vaudevillians
The Good Doctor (1973) - no, Chekov
God’s Favorite (1974) - no, Job (bad play)
California Suite (1976) - no, just funny
Chapter Two (1977)* - yes, based on his second marriage
They’re Playing Our Song (1979) - no, musical
I Ought to Be in Pictures (1980) - no
Fools (1981) - no, old Russian
Brighton Beach Memoirs (1983)* - yes, expressly so
Biloxi Blues (1985)* - yes, time in army
Broadway Bound (1986)* - yes, starting career
Rumors (1988) - no, farce
Lost in Yonkers (1991)* - yes based on childhood
Jake’s Women (1992)* - yes based on ex wives
The Goodbye Girl (1993) - no, musical
Laughter on the 23rd Floor (1993)* - yes based on TV career
London Suite (1995) - no just funny
Proposals (1997) - no
The Dinner Party (2000) - no
45 Seconds from Broadway (2001) - no
Rose’s Dilemma (2003) - no

So it’s actually a smaller proportion than I thought - ten if you include Odd Couple. I think bc the blockbusters and critical hits are autobiographical they overshadow other work.
