This is so fun! You didn't by any chanse get this idea from my post in the 'You Know You're Obcessed With LotR When...'-thread?
Just curious...
As for Kung Pow: that's too easy!
Steve Oedekerk did the screenplay for Bruce Almighty. Jim Carrey plays Bruce, and in Eternal Sunshine of the Spottless Mind he plays Joel Barish. And guess which LotR-character that plays in Eternal-Spottless-Sunshine-thingy! Elijah Wood!!!
And I've got another version of Anna and the King:
Anna and the King -> Tom Felton -> Harry Potter -> Robbie Coltrane (Hagrid) -> From Hell -> Ian Holm!
OR...
Anna and the King -> Jodie Foster -> Panic Room -> Jared Leto -> Requiem for a Dream -> Jennifer Connelly -> Hulk -> Eric Bana -> Troy -> Orlando Bloom -> Lord of the Rings!
Wow, that was a long one...
Next...?
