Indiana Jones and the Last Crusade was the focus of a "Young Indiana Jones" series of young adult novels that began in 1990; by the ninth novel, the series had become a tie-in to the television show. German author Wolfgang Hohlbein revisited the 1912 prologue in one of his novels, in which Indiana encounters the lead grave robber—whom Hohlbein christens Jake—in 1943. The film's ending begins the 1995 comic series "Indiana Jones and the Spear of Destiny", which moves forward to depict Indiana and his father searching for the Holy Lance in Ireland in 1945. Spielberg intended to have Connery cameo as Henry in "Kingdom of
Indiana Jones and the Kingdom of the Crystal Skull by Luke Ross (""), children's novelizations of all four films, the "Indiana Jones Adventures" comic book series aimed at children, and the official "Indiana Jones Magazine". Scholastic featured Indiana and Mutt on the covers of "Scholastic News" and "Scholastic Maths", to the concern of parents, though Jack Silbert, editor of the latter, felt the film would interest children in archaeology. The film was released on Blu-ray Disc and DVD in North America on October 14, 2008 and in the U.K. on November 10. This release includes a two-disc edition Blu-ray, a two-disc special-edition DVD, and a one-disc edition DVD. The
