The iconic playwright, who died Sunday at age 91, saw his play The Odd Couple turned into a movie and two TV series -- starring Tony Randall and Jack Klugman on ABC from 1970 to 1975, and starring Matthew Perry and Thomas Lennon on CBS from 2015 to 2017. "Thank you Neil Simon," tweeted Lennon. Yvette Nicole Brown, who also co-starred on the CBS version, tweeted: "A lot of my heroes are dying. What a sad few weeks this has been. #RIPNeilSimon."
