Good luck to the #SAVESHADOWHUNTERS brigade!

ORIGINAL: Shadowhunters fans are a passionate bunch, that's for sure.

Following the news that the show was cancelled, fans have raised about $20,000 for different charities, shared more than 10 million tweets with #SaveShadowhunters, and even hired a plane to fly over Netflix HQ in a bid to save the Mortal Instruments adaptation.

Now they've gone one step further and have taken out a billboard advert in none other than New York City's Times Square. The advert will appear from 3pm on Friday (June 29) on 42nd Street and 7th Avenue facing east and will last for a whole five minutes.

The series' cancellation was announced earlier this month, with Freeform saying that it "just couldn't make the economics work", and will conclude next year with 10 episodes that make up the second half of season three, as well as a two-part finale (which won't be enough but it's better than nothing).

If you want to join the chorus of people calling for someone to save Shadowhunters but are a bit skint, there's a petition you can sign, which has amassed more than 130,000 signatures so far.

It worked for Lucifer and The Expanse, after all.

Shadowhunters will return in 2019 with 12 episodes left to air, including a two-episode special finale. Netflix airs the show in the UK.
