Co-screen play writer of "The Hitchhikers Guide to the Galaxy" has described Sam Rockwell's interpretation of Zaphod Beeblebrox as "George Bush Meets Freddie Mercury"
"Sam does a lot of research and came to rehearsals having studied a lot of Queen videos. So his Zaphod is a sort of "George Bush Meets Freddie Mercury", which is a horribly frightening combination, and it works beautifully"
The Zaphod Beeblebrox character is the president of the Galaxy.
