After winning the Perrier Award, the creators confounded media sources by refusing to speak out of character, or give real names or backgrounds.

The character is highly conceited and narcissistic, often describing himself through epithets such as "the dream weaver", "shaman", "titan of terror", "The One Man Fear Factory" and "master of the macabre."

Marenghi also guests in the first episode of Dean Learner's talk series, Man to Man with Dean Learner, where he reveals that he lost an ear in an ambulance crash, has written a total of 436 books, and has filmed a new movie, War of the Wasps,[8] featuring most of the cast of Garth Marenghi's Darkplace.

Marenghi has appeared in an episode of the Russell Howard Hour as part of a Christmas special to read a portion of one of his novels, Flay Bells Sting, Are You Glistening?

In The Reel Feedback Podcast #89, Marenghi stated that readers may recognise the titles being the same as his own fledgling efforts in the early eighties.
