This boggles the mind. This reminded me of something I saw on another forum:
How long 'til we have Half-Life: The Movie where Dirk Freeman rescues the world from the evil (not Arabian at all) Combine who are planning to blow up Tower 13? Starring wise-cracking Jim Carey as Dirk Freeman, Megan Fox as Alyx, Samuel L Jackson as Elias, Ben Stiller as Barney Calhoun and the lovable antics of DOG (voiced by Hank Azaria)
Funnily enough, there's no headcrabs as the test audience didn't like them, but G-Man learns a lesson about how even non-humans can learn to care about the environment.
There's also the sexy alien Vortigaunt, and the "hilarious" adventures of the Dr. Breen.
Tell me you wouldn't pay to see that?
