As big TV events go, Crisis on Infinite Earths was one of the most popular crossovers in superhero history. Not only did it combine the might of the five DC shows across The CW, but it also dealt with one of the most dramatic storylines from the original comics that held nothing back when it came to the fates of popular characters.

The entirety of Crisis on Infinite Earths has now aired in the US, but watching every episode in order may be a little confusing. This isn’t a standalone series; viewers have to skip between various shows to catch all five episodes. This is made all the more confusing if you’re based in the UK - as only select shows are available to watch in the UK.

However, there is a way to catch up through using a VPN. Read on to find out how to watch up on all of the Crisis episodes. We also have similar articles to watching the MCU movies and films in order, and the same for all Star Wars films and canon TV. You can also find out how to watch the season 10 finale of The Walking Dead here. 

How to watch Crisis on Infinite Earths in order

There are five episodes to watch, all embedded within the Arrowverse series. Here are which episodes and seasons you need to watch:

  • Part 1 - Supergirl, Season 5, Episode 9
  • Part 2 - Batwoman, Season 1, Episode 9
  • Part 3 - The Flash, Season 6, Episode 9
  • Part 4 - Arrow, Season 8, Episode 8
  • Part 5 - Legends of Tomorrow, Special Episode (prelude to Season 5)

What do I need to catch up on?

If you’ve not kept up with all the Arrowverse shows in their entirety (we can’t blame you, it is a lot) then here are the key episodes you should check out before you start watching Crisis on Infinite Earths.

Firstly, 2018’s crossover event Elseworlds is worth catching up on, as it introduces several plot points and characters that are revisited in the Crisis storyline. Plus, you’ll also get to see some of the character interactions and existing relationship dynamics.

You can get away without watching the latest seasons of Supergirl, Batwoman and Legends Of Tomorrow, but it’s worth watching the most recent series of both Arrow and The Flash, and the series 7 finale of Arrow to understand exactly what’s going on.

In addition, Black Lightning's Earth Crisis episode (season 3, episode 9) directly precedes Part Three of Crisis on Infinite Earths, so you may want to consider adding that to your watch list after watching Part 2. You can catch up on that episode of Black Lighting on Netflix.

Where to catch up on all the episodes

In the UK, there's a selection of episodes of Crisis on Infinite Earths that are available to watch on Sky One and through Now TV's Entertainment Pass (£8.99 per month). Sky subscribers should be able to find them on the library, and Now TV owners can watch the episodes via the links below:

You may notice that Part 1 (Supergirl), Part 2 (Batwoman) and Part 4 (Arrow) are missing from that list. First of all, E4 has the rights to Batwoman and is currently airing episodes on a weekly basis. The channel is airing the second part of Crisis on Infinite Earths once all other episodes of Batwoman have aired, which means that it won't be available to watch until August in the UK.

As for Supergirl and Arrow, Now TV has sadly taken season 5 of the former and season 8 of the latter off the platform altogether, so both Part 1 and Part 4 of Crisis is now impossible to stream in the UK. However, there is a workaround to watch some of these episodes.

Both Part 2 and Part 4 are available to watch on The CW website, alongside two ‘Aftermath’ talk shows in which cast and crew discuss the overall storyline and more tidbits. Here's the links to The CW episodes of Crisis that are available right now:

If you’re based in the UK, there is still a way to access The CW catchup service through downloading a VPN. Using a VPN assigns the user a brand new IP address, which can allow the user to appear as if they’re browsing from another country.

For the best range of service, performance and price, we recommend downloading NordVPN, or ExpressVPN. You can check out other options on our list of the best VPNs for streaming. We also have a list of free VPNs, however the limited range of servers will make streaming quite difficult.

Simply download a VPN, choose a US server, open up a new browser and head on over to The CWTV website. If you’d like more detailed instructions, you can find these in our guide to watching The CW in the UK.

Meanwhile, users in the US can do the reverse and use a VPN to access Now TV for parts 1, 3 and 5 whilst watching the rest on The CW website.

The process if basically the same, but instead of choosing a US sever, you connect to a UK one and then sign up for an Entertainment Pass with Now TV. You get a seven-day free trial with the pass, so you don't even have to spend a penny. You can find further details in our guide to watching Now TV abroad.

Sadly at the moment Part 1 of Crisis is impossible to stream for free, but both UK and US viewers can purchase individual episodes of Crisis on Infinite Earths through both Amazon UK and Amazon US

Alternatively, in the UK you can go old school and buy all the episodes on the official Crisis on Infinite Earths DVD, which also has some extra featurettes. You can get this from Amazon UK and HMV.
