Christine Taylor (Ben Stiller's wife) is
not Marcia Brady (blasphemy!)!!
The Brady Bunch Movie (1995) is pagan idol worship!
The real Marcia Brady is
Maureen McCormick
and that is who will be appearing on the new Celebrity Fit Club.
The rest of the CFC lineup is
here
Oh and P.S.:
None of the actresses who played the female Brady children have ever done porn. The other two would be
Eve Plumb (Jan Brady) 
and
Susan Olsen (Cindy Brady)
