Really stupid and/or genius idea

[ShanghaiOrange]

"Apocalypse Now" combined with "The Sound of Music"
"The Sound of Apocalypse" or "The Sound of Darkness" or something.

-One woman's journey down the Danube to find Colonel Von Trapp, kill him, and take care of his kids.

"The hills are alive with the smell of napalm!"

Boat Trip + Ghost Ship = Ghost-Boat Ship-Trip

Cuba Gooding Jr. and Horatio Sanz go on a cruise only to realize it's a gay ghosts singles cruise. Just imagine the gay ghosts from Victorian Era England. Oh man... that would be hilarious. I see Will Ferrel in one of those roles.

[Ghostboy]

For the record, I caught a bit of Boat Trip, and its as bad (or even worse) as you might expect...but Will Ferrell still managed to completely crack me up in his little cameo.

Ferrel has a cameo? What does he do?

Another idea:

12 Angry Monkeys: A time-traveling court room drama.

[Born Under Punches]

A lonely, malcontent monster on his way to scare a child inadvertenly falls in love to the wife of a killer on death row.  Their relationship threatens his home and tests his existential being.

Monster's Ball, Inc.

Coming soon to a theater near nowhere!

I got these from a Fark.com photoshop session a while back.  Not exactly the same thing, but some funny things nonetheless.  Some of the really good ones were gone but I found a few pretty good ones still up.
