<Li> Harrison Ford as Indiana Jones: The archaeologist adventurer who seeks to rescue his father and find the Holy Grail . Ford said he loved the idea of introducing Indiana's father because it allowed him to explore another side to Indiana's personality: "These are men who have never made any accommodation to each other . Indy behaves differently in his father's presence . Who else would dare call Indy' junior'?" <Ul> <Li> River Phoenix as the teenage Jones .

Spielberg had Connery in mind when he suggested introducing Indiana's father, though he did not tell Lucas at first . Consequently, Lucas wrote the role as "a crazy, eccentric" professor resembling Laurence Olivier, whose relationship with Indiana is "strict schoolmaster and student rather than a father and son". Spielberg had been a fan of Connery's work as James Bond and felt that no one else could perform the role as well . Spielberg biographer Joseph McBride wrote, "Connery was already the father of Indiana Jones since the series had sprung from the desire of Lucas and Spielberg to rival (and outdo) Connery's James Bond movies ." Connery initially turned the role down as he is only twelve years older than Ford, but he relented . Connery--a student of history--began to reshape the character, and revisions were made to the script to address his concerns . "I wanted to play Henry Jones as a kind of Sir Richard (Francis) Burton," Connery commented . "I was bound to have fun with the role of a gruff, Victorian Scottish father ." Connery believed Henry should be a match for his son, telling Spielberg that "whatever Indy'd done my character has done and my character has done it better". Connery signed to the film on March 25, 1988 . He improvised the line, "She talks in her sleep", which was left in because it made everyone laugh; in Boam's scripts, Henry telling Indiana that he slept with Elsa occurs later . <Ul> <Li> Alex Hyde - White as Young Henry Jones Sr . </Li> </Ul> </Li>
