Four-legged supernatural detective Scooby-Doo is not a creature usually associated with adults-only viewing. But in a Facebook message to commemorate the 15th anniversary of 2002's Scooby-Doo film, the movie's screenplay-writer, Guardians of the Galaxy director James Gunn, has confirmed that the Sarah Michelle Gellar-starring movie was originally given an R-rating.

"I had loved the character of Scooby-Doo since I was a kid and was excited at the prospect of making a live action film with 2002's cutting CGI technology(!!)," recalls Gunn. "Yes, it was not exactly what we planned going out — I had written an edgier film geared toward older kids and adults, and the studio ended pushing it into a clean cut children's film. And, yes, the rumors are true — the first cut was rated R by the MPAA, and the female stars' cleavage was CGI'd away so as not to offend. But, you know, such is life. I had a lot of fun making this movie, regardless of all that. And I was also able to eat, buy a car, and a house because of it."

Gunn also reveals that, following the success of Scooby-Doo, he was asked to work on other big screen adaptations of animated TV shows, but instead chose to write the script for Zach Snyder's debut movie, the blood-splattered 2004 remake of George A. Romero's Dawn of the Dead.

"I was offered every movie you can imagine," writes Gunn. "Like, uh, the Jabberjaw movie, and The Jetsons movie, and the Captain Caveman movie. I was offered tons of money to do all of these things. So, of course, me being me, I chose to write Dawn of the Dead. Go figure out my brain, who knows."
