Can it be porn?
It can be whatever you want.
Star the same cast and you can call it “It’s a Retirement”.
I would insist that it NOT be porn if it’s the same cast. A naked Ann Jillian alone at this point would traumatize me for thousands of dollars worth of therapy.
What? I don’t think that she’d be that bad.
$50 and time served… in hell.

Three’s Company: the Movie-
Two single young women in L.A. who need a third roommate choose a straight man their own age. The landlord absolutely could not care less so long as he passes the credit and criminal background checks. Makes Guinness Book of World Records as the shortest movie of the decade.
OR…
You could star Miley Cyrus, Lea Michele, and Eminem, with Joe Pesci and Roseanne as the Ropers. And Eminem as Jack has just been released from prison… hmm. That might work.
Hey, remember THE FALL GUY, with Lee Majors?
In Fall of 2010: THE FALL GUY, with Lee Majors.
I was going to say that when the Ropers go to run his credit and criminal background checks they can’t because according the credit and criminal agencies, there is no such person as Jack Tripper.
