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 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, 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 here.

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's 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 currently one episode left of Crisis on Infinite Earths that is available to watch on Sky One and through Now TV's Entertainment Pass (£9.99 per month). Sky subscribers should be able to find it on the library, and Now TV owners can watch the episode via the link below:

As you may notice, all the others parts are missing from that list. First of all, E4 has the rights to Batwoman and was airing the episodes on a weekly basis. Part 2 was available on All 4, but sadly this episode has now expired. 

As for Supergirl, The Flash and Legends of Tomorrow, Now TV has sadly taken off the most recent seasons off the platform altogether, as well as the Crisis episode of Legends of Tomorrow. However, there is a workaround to watch Part 2 in the UK. 

Both Part 2 and Part 4 are available to watch on The CW website - you can find the direct links below:

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 allows the user to appear as if they’re browsing from another country.

For the best range of services, 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. If you're in the US, you should be able to access The CW website through your normal browser. 

Sadly at the moment parts 1, 2 and 5 of Crisis are 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.
