An idea for a movie

A mysterious radioactive meteor falls to Earth, causing the recently dead to rise as zombies and attack the living. In a desperate attempt to save humankind, a team of scientists assembles the ultimate fighting force: a cowboy, a ninja, a knight of the round table, a bomb-heaving anarchist, a shaolin monk, a riot grrrl and a mexican wrestler. Together they must battle their way through the zombie hordes to the smoking crater where the meteor lies and destroy it.
