Premiere date: Thursday, August 31 at 3am ET / 12am PT / 8am BST / 5pm AEST
TV Network: HBO

International streams: Binge (AUS)

Ground down by a world devoid of joy – which, to you and me, looks a lot like this one – Fionna's nights are spent dreaming of a more stimulating approach to life, until one day she and her trusty cat Cake are spirited away on an adventure across a multiverse that had previously only existed in her mind.

Dyed in the wool Adventure Time fanatics will already be familiar with the duo, but for those of you that missed their fleeting appearances on the show, Fionna and Cake are inverse versions of Finn and Jake, who were born out of the Ice King's desire to read steamy fan-fiction to his favourite human and dog. 

Despite only appearing in five further episodes across the show's 283-strong run, they won a place in fans' hearts, and early reviews point to Fionna and Cake being far more mature and earnest than the often wacky and outrageous Adventure Time.

That's not to say that there isn't splodging, bashing, squishing and body-swapping galore, because there is that and more, but the protagonists' thirst for escape set against Simon Petrikov's crushing despair stands to lend Fionna and Cake a bittersweet significance that's likely to strike a chord with viewers. Read on as we explain how to watch Fionna and Cake online where you are.

How to watch Fionna and Cake in the US


Adventure Time: Fionna and Cake premieres with a double-header at 3am ET / 12am PT on Thursday, August 31. It's available to watch on Max in the US, with a pair of episodes arriving at the same time each week.

There are three Max price points: $9.99 a month with commercials, the $15.99 commercial-free subscription – both offering HD video quality – and the Ultimate Ad-Free plan, which at $19.99 provides 4K streaming, Dolby Atmos audio, and the ability to download up to 100 titles to watch offline.

There’s also the option to save up to 20% when you subscribe to an annual plan. That’s $99.99 for the ad-supported plan, $149.99 for the ad-free option, or $199.99 to go all-in with the Ultimate Ad-Free plan. Either way, when you go annual you essentially bag yourself two months’ worth of free streaming.

You'll also get access to a huge library of top-drawer entertainment, including critically acclaimed series Winning Time and Winning Time Season 2, The Last of UsThe White Lotus, Abbott Elementary and Game of Thrones, award-winning animation from Studio Ghibli, DC Universe shows like Peacemaker, Doom Patrol and Harley Quinn. All that, plus epic blockbusters such as Avatar: The Way of Water and all 8 Harry Potter movies.

The 7-day Max free trial has long since been discontinued. But, if you're a current HBO Now subscriber or pay for HBO through your cable provider, you could be entitled to Max at no extra cost.

Devices compatible with Max include iPhone and Android devices, Apple and Samsung TVs, PlayStation 4 and Xbox One consoles, Chromecast and Chromebooks, and laptops and PCs. Max on Roku and Amazon Fire Stick are also available.
