Over the course of his acting career, Harrison Ford has starred in numerous critically acclaimed movies and played many beloved characters, but there is one thing that has been sadly missing from his catalog. Ford’s breakthrough in Hollywood came when he starred as Bob Falfa in George Lucas’ American Graffiti. Although the 1973 comedy-drama certainly isn’t what Ford is most known for, it helped build his relationship with Lucas. Consequently, American Grafitti was a key factor in Ford securing the role of Han Solo in Star Wars in 1977, which was when the actor truly rose to prominence.
