PS: Favorite Blockbuster Before There Were Blockbusters (Ready)

Which of these selected films* that preceded the "blockbuster era," is your favorite blockbuster (event film) that debuted before the term was widely used?
 

A blockbuster is a work of entertainment—typically used to describe a feature film produced by a major film studio—that is highly popular and reaps a significant financial windfall. In 1975, the usage of the term "blockbuster" for films came into widespread use to describe Steven Spielberg's 'Jaws'. The film at the time was perceived as ushering in a new era with films typified by fast-paced, exciting entertainment that inspire widespread interest, conversations outside the theater ("buzz"), and repeated viewings. The "blockbuster era" recently eclipsed the half-century mark with the two films that spawned the term turning fifty. Jaws (1975) is generally regarded as the film that started the blockbuster film genre and George Lucas' 'Star Wars' (later retitled as Star Wars: Episode IV - A New Hope (1977)) further cemented it status two summers later in 1977. In reality, event films like these have always existed, even when there wasn't a catchy phrase to describe them.

 * The answer pool is comprised of thirty-five of the top fifty inflation-adjusted North American box office grossing films prior to the debut of 'Jaws' on July 20, 1975.
