As far as sequels go, I would love one to "White Sun of the Desert"(1970, Soviet Union) which is about this soldier just trying to get home from the wars in the 1920's when he stumbles across a harem that needs rescuing. He is such a great character and the movie is such a hoot, that I've always wondered what…

What about "Bye Bye Monkey" starring Gerard Depardieu and Marcello Mastroianni, and featuring a giant inert ape in lower Manhattan which was made two years after Dino de Laurentiis' modern King Kong remake?

Nothing about "Letter to Brezhnev" which is a sweet movie from early in his career wherein Molina played a Russian sailor?

Strange as it may sound, but Alicia's legal advice to Finn on running for State's Attorney reminded me of the Doctor Who serial "The Deadly Assassin"(spoiler) where the Doctor is framed for murder and exploits the loophole of running for President of the Time Lords, so he cannot be summarily executed.
