The Warner Bros, DC Comics, Vertigo and Silver Pictures logos are on black-and-white film, and are accompanied by part of the 1812 Overture, thus forming the impression that V is starting a transmission.
Part of the closing credits is of a red line forming the V symbol, with characters' faces appearing in the red line alongside the actors' credits.
After the closing credits, the Virtual Studios logo appears. This was done deliberately, to emphasize the V motif.
There are no opening credits, only the company logos and the title of the movie.
