The 1970s and 1980s witnessed a shift towards blockbuster films, which were high-risk, high-reward productions that aimed to attract large audiences. Studios like Steven Spielberg's Amblin Entertainment and George Lucas's Lucasfilm produced iconic films like Jaws (1975), Star Wars (1977), and Indiana Jones (1981). These films not only achieved massive commercial success but also spawned franchises, merchandise, and theme park attractions. The blockbuster era marked a significant change in the industry, as studios began to focus on creating immersive experiences that extended beyond the screen.
