Wow, I am wondering who optioned it? A producer, a composer?
For those that don't know anything about the property here is a brief synopsis of the plot:
Fred and Sharon Cox's marriage is in for a colossal change. When they innocently embark on private Japanese lessons, little do they know they'll each have an affair with their alluring tutor, Hana Yoshi. And little do they know that their moody teenager, Kevin, is wildly passionate for one or the other of their twin Salvadoran housekeepers and about to run off with her. Everyone in the Cox house, for a while, seems to be loving in secret...until the truth and romantic consequences unfurl hilariously in All Kinds of Love
Reiner had a stage hit with "Enter Laughing" which was adapted by Joseph Stein from his autobiographical novel back in 1963. Reiner and Stein then collaborated on the screenplay for the 1967 film adaptation. The play was then adapted as a musical in 1976 as "So Long, 174th Street" but it was unsuccessful in that incarnation. The book for the musical was also by Joseph Stein and the music and lyrics were by Stan Daniels.
