In non-Chayefsky work:
When the movie first came out in 2011, were film-savvy people here generally aware that the 2011 movie called "Just Go With It," starring Adam Sandler and Jennifer Aniston, was a remake of "Cactus Flower," which starred Walter Matthau and Ingrid Bergman, and Goldie Hawn in her Oscar-winning supporting role.
I guess "Just Go With It" was a real hit, even though not well-respected: It grossed over $200-million, with an $80-million budget, according to wikipedia.
When I watched it on TV, I thought, boy, this premise sounds familiar - and then saw it was an actual remake of "Cactus Flower."
