Welcome to our Marvel movie countdown to Avengers: Infinity War.
Between now and the film's release on 27th April we're recapping one Marvel blockbuster a week, which means you will be fully up to speed on the Marvel Cinematic Universe (MCU) by the time Infinity War arrives on your screens.
This challenge initially came from our American friends. To make it work, here’s what we suggest...
Week one: Iron Man
We're getting things started by venturing back to the birth of the MCU, and the debut of one Robert Downey Jr. as "genius-billionaire-philanthropist", Tony Stark.
Week two: The Incredible Hulk
Following hot on Iron Man's heels is Edward Norton's solo outing as conflicted rage monster scientist Bruce Banner.
Week three: Iron Man 2
Tony Stark's sophomore adventure is next, one that sees the big screen debut of Scarlett Johansson's kick-ass Black Widow.
Week four: Thor
The MCU expands its ranks as Chris Hemsworth's God of Thunder makes an impact, alongside Tom Hiddleston as his sneaky step-brother Loki.
Week five: Captain America: The First Avenger
This is where it all began for the Avengers initiative, in a rousing World War II adventure that introduces us to super-soldier Steve Rogers (Chris Evans).
Week six: Avengers Assemble
Our Marvel heroes get together for the first time in Avengers Assemble, Joss Whedon's franchise debut and the culmination of phase one of the MCU.
Week seven: Iron Man 3/Black Panther
Phase three begins with Tony Stark's third and final solo adventure (for now), which pits him against the villainous Mandarin (Ben Kingsley) as Shane Black directs.This week also sees the release of Black Panther so we’ll have to cheat a little bit and ask you to watch TWO Marvel epics. But hey, who’s complaining?
Week eight: Thor: The Dark World
Asgard is under threat in Thor's second adventure, directed by Game of Thrones regular Alan Taylor.
Week nine: Captain America: The Winter Soldier
Noble Steve Rogers must adopt to the morally murky 21st century in this exciting follow-up, the first Marvel movie from Infinity War filmmakers Joe and Anthony Russo.
Week 10: Guardians of the Galaxy
We can't wait to see the mash-up of the irreverent Guardians with the original Avengers ensemble in Infinity War. But before we do, it's time to journey back to their infectiously groovy big screen debut.
Week 11: Avengers: Age of Ultron
The embattled Avengers must go to war with villainous A.I. Ultron (James Spader) in Joss Whedon's final Marvel blockbuster.
Week 12: Ant-Man
Phase three of the MCU culminates with a snazzy, witty mash-up between the superhero movie and the spy caper, as Paul Rudd's shrinking thief Scott Lang enters the picture.
Week 13: Captain America: Civil War
Making previous Marvel battles look like playground scraps, the Russos' hugely ambitious, expansively realised epic hinges on the brewing tension between Tony Stark and Steve Rogers.
Week 14: Doctor Strange
It's time to enter the cosmic realm as Benedict Cumberbatch's magical Sorceror Supreme unlocks previously unseen dimensions of the Marvel universe.
Week 15: Guardians of the Galaxy Vol. 2
It's time to crank up Awesome Mix. Vol 2 as Star Lord (Chris Pratt) and the gang face another blend of showstopping pop tunes, interstellar action and heartfelt family drama.
Week 16: Spider-Man: Homecoming
Spidey finally joined the MCU in 2017 and star Tom Holland's fledgling adventure was a joyously entertaining wonder. So prior to his return in Infinity War, it's time for a recap.
Week 17: Thor: Ragnarok
Hunt for the Wilderpeople director Taika Waititi gave us the most radical shake-up of the MCU in years, remoulding the portentous God of Thunder's adventures as a hilariously wacky out and out comedy.
Again a bit of cheating is needed here as you’ll be watching Ragnarok the same week as the release of Infinity War. Double bill, anyone? Might be worth getting a bit of humour in before the world comes to an end...
While we’ve opted to go by release date, the viewing order is up to you. You can also group films by superhero, comedy level or go completely rogue. We won’t judge! If you’re doing the Marvel Challenge be sure to tweet us and let us know at @Cineworld.
