Joe Cornelius, who plays the feature's title character, provides a quite different perspective on Crawford's actions and demeanor during filming. As a professional wrestler in England, Cornelius performed in the ring for 20 years as "The Dazzler" and was chosen to portray Trog due to his physique and athletic abilities. His role provided him with numerous opportunities to observe Crawford both on and off camera. Forty-five years after the release of the film, in an interview arranged and video-recorded by the British Film Institute (BFI), he shared publicly for the first time his experiences working on the production and more specifically with the veteran actress. That interview occurred in September 2015, just prior to a screening of "Trog" by BFI in one of its film retrospectives. It was conducted by the American director and writer John Waters, a notable promoter and creator of underground or "transgressive cult films", as well as a fan of many other types of low-budget, more mainstream productions like "Trog". In his interview with Waters, Cornelius takes exception to reports that Crawford used "idiot cards" and was periodically drunk during filming. The former wrestler says he saw no use of such cards by her; and he describes Crawford as "great" to work with, consistently on time and "lovely" on the set, as generous in giving gifts to the crew, and how for years after completing "Trog" she sent him a personal card every Christmas. While he concedes that Crawford "possibly" had vodka in her Pepsi-Cola container, he also states that he never saw her drunk or unable to perform for any reason during the film's production.
