No sheep were probed during the making of this film
After the credits, a man in a hazard suit is shown approaching the keyboard from the start of the film. He removes the suit to reveal himself as Professor Brian Cox, and proceeds to play "Things Can Only Get Better" by D:Ream. (Before becoming a physicist, Brian Cox was the keyboard player with D:Ream.)
There is a mid credits scene.
The main title simply reads FARMAGEDDON.
Aardman variation: At the beginning of the film, we see a sheep at a keyboard. He begins to play four notes of "Life's a Treat", while grouped letters of the Aardman logo appear. When it reaches the final note, the word appears in whole. He presses a note forming the star, takes the music book and walks away. The lights dim out and the word Aardman fades out as the star zooms into outer space, turning white in the process.
The end credits feature colored bars which resemble the control panels on Star Trek the Next Generation.
