Want to see Uranus? July 4 could be your best chance in decades

We didn't realize it at the time — nobody ever does — but the '90s were a vintage era in Hollywood.It was a time when major studios were happy to take a punt on original scripts, knowing that people would, as often as not, buy theater tickets to watch quality releases. Good movies will always be made, of course — just as even the most golden of ages produce their fair share of stinkers — but this was a time when the Venn diagram circles labelled 'acclaimed' and 'popular' intersected on a satisfyingly regular basis.But beyond the critic-friendly fare produced by the likes of Quentin Tarantino, the Coen Brothers, Paul Thomas Anderson, and Martin Scorsese, this was also a peak period for popcorn-friendly action movies… and especially sci-fi action movies. Highbrow reviewers didn't always appreciate their brilliance back then, but looking back all these decades later, many of the best examples still stand up now."Independence Day" — which turned 30 last week — isn't even the best entry in the genre, but it repeatedly shows why the end of the 20th century was the perfect time to experience blockbuster thrills and spills in a multiplex. And, spoiler, there was barely a superhero in sight.The '80s had teed up the subsequent decade's action explosion perfectly. On one side was the family-friendly fare championed by George Lucas and Steven Spielberg, timeless movies like the "Star Wars" sequels, "ET", "Back to the Future," and "Indiana Jones" that produced a generation of budding cinephiles. They were complemented by the more rugged, violent, and grown-up adventures popularized by the likes of "Aliens", "Predator", and "Die Hard".

Its poster boys were uber-producers Jerry Bruckheimer and his late filmmaking partner Don Simpson, whose "high concept" ethos distilled movies down to a pithy elevator pitch you could squeeze into a single sentence.But the company's undisputed classics of the era make it obvious they were on to something — "Crimson Tide" (feuding submariners try to avert World War III), "The Rock" (rogue marines capture Alcatraz to hold San Francisco to ransom) and "Con Air" (a bunch of prisoners capture their transport plane). It's a formula that also worked for "Speed" (a bomb will explode if a bus goes under 50mph), "Twister" (scientists chase tornadoes across America), and "Under Siege" ("Die Hard" on a boat).

Let's start with their own high concept, easily summed up as a modern-day spin on HG Wells' "The War of the Worlds", but with bigger spaceships and a more pronounced fetish for major landmarks.Speaking to the Guardian, Devlin recalled Emmerich's original idea. "[He said], 'What if we woke up tomorrow morning and we walked outside to get the newspaper and above it was a 15-mile-wide spaceship blotting out the sun for an entire city?' Then he turned to look at me and goes, 'I think I have our next movie.'""Independence Day" didn't need to be part of a major franchise to get noticed. The teaser trailers, with their carefully choreographed moments of tourist hotspot destruction, were enough for that, as was the brilliant sci-fi movie poster, which saw Manhattan dwarfed by a flying saucer. "The question of whether or not we are alone in the universe has been answered," said the wonderfully doom-mongering tagline.
