George Lucas and Steven Spielberg are responsible for 7 of the top 10 highest-grossing films of the 1980s.
Not only that, but they are also responsible for 4 of the top 5 films of that decade! The seven films include: E.T. the Extra-Terrestrial, Star Wars Episodes V & VI, and the Indiana Jones trilogy. Spielberg also produced Back to the Future. Lucas began the decade with the completion of The Empire Strikes Back (1980), his first Star Wars sequel, and then collaborated with Spielberg on a new project called Raiders of the Lost Ark (1981), which was released the following year. Spielberg then moved on to direct what would be the most financially successful film of the decade, E.T. the Extra-Terrestrial (1982), while Lucas completed his Star Wars trilogy with the release of Return of the Jedi (1983). The next year, the pair got back together for the Raiders prequel Indiana Jones and the Temple of Doom (1984), before Spielberg signed on as executive producer of Back to the Future (1985). This ended their streak of rabid success for a couple of years. Lucas produced a couple of forgettable TV shows about Droids and Ewoks, and Spielberg directed a pair of less lucrative films. The honeymoon was not over just yet, though - the dynamic duo reunited to sneak one final blockbuster to close out the decade with Indiana Jones and the Last Crusade (1989).
Here's a list of the top 10 films of every decade.
