His Real Career Only Lasted From 1971 through 1982
Well...its a theory of mine.
After a number of years getting his foot in the door of Hollywood(at a VERY young age) and setting up shop Universal in their cookie-cutter TV production department(which mainly fed shows to NBC but occasionally made an ABC movie-of the week), Spielberg really hit big(on TV only) in 1971.
Part of it was that Spielberg directed "the very first episode of the Columbo series for broadcast," and it made a splash with its highly stylized, Hitchcock sound-and-image sequence. (Historians note that Columbo on TV first appeared in a TV movie in 1968 and then a pilot in early 1971, but was green-lighted for series in late 1971.)
But Spielberg's BIGGER splash came on a few months after the Columbo episode: an ABC movie-of-the-week TV movie(90 minutes less commercials) that felt like a REAL movie, but o f a specific type.
For the most part, TV movies were too short, too cheap, and too badly written to feel like movies(Even the "great" social drama TV movies about gays and abortion and incest were...social drams) But Duel went in a different direction. It had no "plot" to detail, little dialogue(save the protagonist's ever-more panicked narration) and was essentially "a 90 minute action set piece" that COULD power a movie. The story is about a solo motorist(Dennis Weaver) being chased by a big, creepy, RUSTY ol' big rig all over the California desert and hills. near-feature length.
And it WORKED. I was around at that time, and movie fan teens flocked to Duel -- as a school topic and in its major rerun -- as "the second coming of Hitchocck"(who was old and almost retired, anyway -- though his creepy R-rated comeback hit Frenzy, opened in theaters just a few months after Duel))
Some "filler footage" was pumped into Duel, it became a theatrical feature in Europe, and Universal worked on "what to do" with Spielberg.
His debut film --"the Sugarland Express" (1974), a car-chase DRAMA with Goldie Hawn in a serious (and seriously irritating) lead, was a big downer and a big flop BUT it established Spielberg's skill with action(lots of cars after his one truck) and, crucially, got a score from John Williams -- who would become an equal partern in the Spielberg auteurship.
Lucky for Spielberg, the producers of The Sugarland Express -- Richard Zanuck and David Brown -- tapped him to direct Jaws for 1975 release and -- Spielberg was on his way to superstardom, director-wise. But key was that DUEL, not Jaws, was the first action thriller classic of the bunch.
Spielberg took his "highest grossing movie of all time" clout to make another blockbuster -- "Close Encounters of the Third Kind" -- as indulgent in its overlong making as Jaws had been " a studio pressure project." But it was a hit at the end of 1977, only slightly overshadowed by Star Wars in the summer of 1977.
Weird bad news for Spielberg "at the Oscars": (1) Jaws was nominated for Best Picture, but Spielberg not for Best Director and then later (2) Spielberg was nominated for Best Director for Close Encounters , but the movie was NOT nominated for Best Picture.
With the one-two-three punch of Duel-Jaws-Close Encounters under his belt -- AND with Hollywood out to champion new young superstar directors to replace Hitchcock et al, Spielberg took some Animal House people and some extra SNLers and made a "surprise flop" -- the WWII comedy 1941, The action is great in it, and there is SOME comedy, and it looks better today but back THEN...the long knives came out for "cocky young Spielberg."
The comeback Hitchcock needed at age 72 with Frenzy, Spielberg got in his early 30s with "Raiders of the Lost Ark." His pal George Lucas co-wrote and produced it and the press was: "Lucas is keeping Spielberg on schedule and a tight budget." It was the biggest hit of 1981, and just one summer later, Spielberg got the biggest hit of "all time" (beating Star Wars and Jaws) with the super emotional family tearjerker ET.
To have been around when Raiders and ET dominated only about a year's time of release was to feel like Spielberg had ARRIVED, was IT. Hitchcock died in 1980. Raiders came out in 1981. ET came out in 1982. Spielberg was king(yes it was called the Lucas-Spielberg 80s, but Lucas pretty much stuck to Star Wars sequels, and a coupla so-so releases.
..still I say: Spielberg's REAL career -- his superstar career, his impact-on-audiences career -- ended in 1982 with ET. A run that includes Columbo, Duel, Jaws, Close Encounters, Raiders of the Lost Ark and ET really WAS a great run, but Spielberg never really was that great again.
The trouble hit immediately in the summer after the ET summer of 1982: Spielberg was the producer of The Twilight Zone movie -- four different stories directed by four top directors(Spielberg, John Animal House Landis, George Mad Max Miller, and Joe "Gremlins" Dante.)
