The secrecy and security surrounding the plans for Derp Con were heightened well beyond a normal fan convention, given the sheer scale of the production, which sprawled throughout the five acre space at Paramount Studios, which has been the location for some of the biggest movies in Hollywood’s history including Spiderman 3, Mission Impossible 3, Ghost, Forrest Gump, Coming To America, Saturday Night Fever, Godfather and The Great Gatsby to name just a few.

Organisers managed to keep everything firmly under wraps until the day itself leaving fans and media gasping in amazement at the Derpness of this epic one-of-a-kind set, which has been one of the most ambitious undertakings ever for any band convention.
