Tomorrow at Comic-Con, several shows based on DC Comics will all gather in Hall H for Superhero Saturday Night, a three-hour panel that includes Arrow, The Flash, Gotham, Supergirl and DC's Legends of Tomorrow. On the eve of that mega-panel, The CW has released a new trailer for DC's Legends of Tomorrow, that also features footage from Arrow and The Flash, along with comparisons to these scenes from their comic book counterparts. As you can see in the video below, several of these scenes are lifted directly from the comics they were inspired by.

The three-hour panel will include Q&A sessions with cast members and producers from Arrow and The Flash, along with a special video presentation from DC's Legends of Tomorrow. It isn't known if production has already started on DC's Legends of Tomorrow, so we're not quite sure what will be shown in this video presentation, but stay tuned to find out what exactly is shown. If you are in San Diego for the con, the panel takes place from 8 PM to 11 PM in Hall H.

When heroes alone are not enough... the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat - one in which not only is the planet at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known? DC's Legends of Tomorrow is set for a mid-season debut on The CW, and you can check out this unique trailer below.
