The fourth season of Supergirl promises to be even more fun and exciting than before. A sign of good things to come for the popular CW series.

While Warner Bros/DC Comics has been keeping pretty mum about a Man of Steel sequel, it looks like a different Kryptonian is heading to the big screen in a solo adventure as a Supergirl movie is now in the very early stages of development.

In her multi-hyphenate career as a model, musician, and actress, Ruby Rose has travelled all around the world. And now she's heading for a place very few have ever been: Gotham City. As officially revealed last night, the Australian-born Rose has been cast to play Kate Kane aka Batwoman in The CW's upcoming Arrowverse crossover event before spinning off into her own DC Comics TV series alongside Arrow, The Flash, DC's Legends of Tomorrow, and Supergirl.

It may have been a tad bit uneven, but season 3 of Supergirl ended with some tantalising new mysteries to dig into. The primary enigma being a new version of Kara who appeared at the end, a Russian Supergirl whose appearance will be a nod to the classic Superman Elseworlds story Red Son.

The CW's upcoming big crossover between Arrow, The Flash, DC's Legends of Tomorrow, and Supergirl is set to introduce popular comic book character Batwoman in live-action fashion for the first time. That's not the last we'll see of this modern comic book icon though.

There’s still a ton of action, intrigue and comic book references to feast on every week, and the core shows making up that world of leather and trippy sci-fi are coming back this October. While more plans for Arrow, Supergirl, The Flash, Legends of Tomorrow and Black Lightning will be revealed at Comic Con this week, DC’s YouTube channel did drop a few new details on what to expect this year.

This might be a day late, but honestly, no one was going to be reading this when the last public holiday until mid-June beckoned. Here's everything that will be hitting Netflix screens over the next month.

Here’s a look back at several times when Superman exposed the world to his own personal brand of Kraptonite.
