Step 1 : Introduction to the question "James Gunn, writer and director for "The Guardians of the Galaxy" films, also wrote the screenplay for which live-action cinematic remake of a children's cartoon?"
Ruh-roh, Raggy! Before James Gunn would wow Marvel fans with space-bound spectaculars in the "Guardians of the Galaxy" franchise, he penned screenplays for two Scooby-Doo films.

And he would've gotten away with it too if it wasn't for these meddling trivia questions! Source: IMDb
