By the time the pilot episode of CBS' new DC Comics-based show Supergirl screened at San Diego Comic-Con 2015, quite a lot of people had already seen the leaked version that appeared online in mid-June. The pilot has so far received mixed responses from both audiences and critics, with some offering high praise and others not quite so enamored.

Of course, a pilot episode isn't always the best measure of what a series will be like. A pilot often acts as a pitch for a full series, meaning that the writers have to cram in a lot of backstory and basic character set-up, while further episodes have a bit more breathing room. As such, the real test of Supergirl will be whether or not showrunners Greg Berlanti, Andrew Kreisberg and Ali Adler can keep audiences hooked throughout the first season.

That mission begins now, as Adler has announced on Twitter that the second episode of Supergirl begins filming this week. The rest of the season will reportedly introduce super-villain Reactron and Lucy Lane a.k.a. Superwoman, and Peter Facinelli recently joined the cast as businessman Maxwell Lord. Now that filming has started up again, we're expecting to hear more casting news in the coming weeks.

To celebrate the occasion, CBS has released a new poster for Supergirl featuring what appears to be a tribute to comic book artists who haven't quite got the hang of perspective. Thus, Kara soars through the air majestically with one massive arm that ends in a fist the same size as her head. There's also something rather strange going on with her knees. Let this be a lesson that Photoshop duties shouldn't be left to the office intern.

Supergirl stars Melissa Benoist as Kara Zor-El, a Kryptonian trying to live a normal life in National City under the Earth name Kara Danvers. When a potential disaster forces Kara to show off her formidable powers, she decides to embrace her superhero status in order to help the people of Earth. The show also stars Mehcad Brooks, Calista Flockhart, David Harewood, Jeremy Jordan and Chyler Leigh.

Since Kreisberg and Berlanti spearheaded the creation of the shared DC TV universe over on The CW, there has been plenty of discussion and speculation surrounding the possibility that Supergirl will eventually join The Flash, Arrow and Legends of Tomorrow as part of that universe. This has neither been confirmed nor completely written off yet, so it will be interesting to see whether Supergirl's first season keeps that option open or clearly defines itself as a standalone show.

Supergirl premieres on CBS at 8:30 p.m. EST on October 26th, 2015. It will air at 8 p.m. EST on Mondays thereafter.
