The cast of the beloved Justice League animated TV series reunited this weekend at Denver Comic-Con.

On hand at the event were voice actors Kevin Conroy (Batman), George Newbern (Superman), Susan Eisenberg (Wonder Woman), Michael Rosenbaum (The Flash), Maria Canals-Barrera (Hawkgirl), and Phil LaMarr (Green Lantern). Carl Lumbly (Martian Manhunter) was unable to attend, so DC veteran Khary Payton (Young Justice, Teen Titans Go!) stood in for him as J'onn J'onzz. The group participated in a panel discussion moderated by longtime DC animation voice director Andrea Romano before taking part in a live read-through of the three part series finale 'Starcrossed', where Earth is overrun by the Thanagarians, Hawkgirl's people. After 'Starcrossed' the show rebooted itself as Justice League Unlimited, a series that maintained the same core of heroes but massively expanded the its scope to virtually every corner of the DC Universe.

Long considered to be among the crown jewels of superhero animation, Justice League and Justice League Unlimited came to define the DC Universe for an entire generation. Over five seasons, the series expanded on the relationship between its already-established animated heroes (Batman and Superman), and presented iconic, thoughtful representations of some of DC's less known characters, like Martian Manhunter - the last survivor of Mars, trying to understand humanity and his new home - and The Flash, here portrayed as the wise cracking Wally West.

The series' most enduring legacy, however, is what it did for Green Lantern John Stewart. Essentially since his creation in 1971, Stewart had been relegated to a secondary, supporting role to the primary human Green Lantern, Hal Jordan. Justice League drastically changed that, breathing more life into John Stewart than 30 years of comics had prior. John's burgeoning romance with Hawkgirl (Shayera Hol) was the most reliably stirring storyline from the early seasons of the show, and the tragic fate of that relationship fueled the climactic 'Starcrossed' finale. It's not difficult to draw a direct line from Justice League's influence to the fact that DC's upcoming Green Lantern Corps movie will feature both Hal Jordan and John Stewart, as equal partners in a sort of buddy cop movie in space.

There's understandably massive anticipation for Zack Snyder's upcoming Justice League live-action film, which is likely to set the tone for the rest of the DC Extended Universe going forward. That movie would be very lucky to enjoy the enduring legacy of the groundbreaking animated series.
