When the Marvel superhero movies reached their box office-shattering climax in 2019, nobody could have predicted the saga's next installment would be a kitsch, black-and-white TV sitcom called "WandaVision."
But a lot has changed since Iron Man and friends saved the world in that summer's all-time record-grossing blockbuster "Avengers: Endgame" (and mopped up some loose plot points in "Spider-Man: Far From Home" shortly thereafter.)
The wildly popular franchise of 23 interconnected movies has ground to a halt along with the rest of the world as Covid-19 shuttered movie theaters, delaying "Black Widow" and other big-screen superhero sequels.
Meanwhile parent company Disney has splashed out billions bringing its biggest franchises and characters to the Disney+ TV platform, as it locks horns with Netflix, HBO Max and others in the spendthrift "streaming wars."
So here to finally push onward the over-arching plot of Marvel's "cinematic universe" is "WandaVision," an oddball and fiercely original series out Friday on Disney+.
It stars witch Wanda Maximoff (Elizabeth Olsen), and other-worldly android Vision (Paul Bettany), two B-list superheroes who struck up an unlikely but fan-favorite romance across several recent Marvel films.
"WandaVision" finds them -- without explanation -- living happily married in the idyllic 1950s town of Westview, which is seemingly lifted straight from an episode of "Bewitched" or "I Love Lucy" (complete with canned laughter track.)
They still have superpowers, but have traded battles with genocidal villains for a cozy world of school fundraisers, neighborhood watch meetings and anniversary dinners.
If that sounds incredibly weird, it is.
"When I first heard the pitch of the show, I was gobsmacked," admitted director Matt Shakman.
"There are so many shows out there on streaming right now -- to find something that feels so special, like it hasn't been done before, that's really rare," he told AFP. "And this definitely is one of those."
- 'Secret sauce' -
Of course, all is not what it seems.
Mystery shrouds the arrival of Wanda and Vision in their bizarre new home, and some neighbors appear to know more than they initially let on.
Trailers suggest that later episodes will hop through time and bring Marvel fans the more familiar popcorn action sequences they have been craving -- and, indeed, scenes shot in color.
Keeping plot under wraps, Marvel has shown press just three well-received episodes, which are remarkable mainly for humorous set-pieces in which the pair narrowly avoid revealing their secret to nosy neighbors.
"The (Marvel) movies are hilarious and that's definitely a huge part of their secret sauce," said Shakman, who drew influence from his background on other TV comedies including "It's Always Sunny in Philadelphia."
"The number one rule that we learned on 'Sunny' is if it makes us laugh, it will make other people laugh."
Beyond the gags, starved Marvel obsessives are itching to find out what has happened to their favorite characters.
Marvel has produced dozens of TV series before, but "WandaVision" is the first confirmed to fit -- somehow -- into the films' grand, shared storyline.
An explosion of fan theories has tried to solve these riddles, not least how the show gets around Vision's death in 2018 film "Avengers: Infinity War."
"There is so much anticipation for the show," said Shakman.
"The 'why' of it all is part of the great mystery of the show," he explained.
- 'Crazy risks' -
"WandaVision" is just the first of a dozen Marvel series in the works for Disney+.
Bosses hope the shows can emulate the small-screen crossover success of "Star Wars" smash hit "The Mandalorian," which has sent subscribers to the new platform in their droves.
But while "Star Wars" films have traditionally stuck to a fairly rigid "space Western" formula, Marvel have never been afraid to experiment, said Shakman.
"They have been taking these crazy risks the whole time -- 'Guardians of the Galaxy,' 'Thor: Ragnarok'... they're constantly playing around with genre and tone and doing things that other people thought were pretty bonkers," he said.
"That worked out great in the end. And 'WandaVision' definitely is a big swing... it's very different."
