Belgian comics artist Joseph Gillain (Jijé) with Leone and Hill on the set of Il mio nome è Nessuno in 1973. At that time, Jijé was working on a comic book adaptation of Valerii and Leone’s farewell Western, but the latter reportedly pulled the plug on that project (some of Jijé’s finished pages and [preparatory] drawings are on view on Inedispirou.com). Conversely, Leone had shown interest in adapting Jijé’s long-running Western comic book series Jerry Spring for the big screen (source: Tanguy et Laverdure, intégrale 8).
