When producer Greg Berlanti revealed that the forthcoming film adaptation of DC's Booster Gold will not be attached to the other films in DC's "extended universe," there was inevitably going to be somebody to ask this question: Could the film potentially tie into Berlanti's TV shows, affectionately known to fans as The "Arrowverse," "Flarrowverse" or "Berlantiverse?"
Berlanti's four DC superhero series -- Supergirl, The Flash, Arrow, and DC's Legends of Tomorrow -- air weeknights at 8 p.m. (except Fridays) on The CW, and their ever-growing, interconnected universe also has ties to a pair of animated series: Vixen and Freedom Fighters: The Ray.
During a recent interview, Berlanti revealed that the Booster Gold movie will not be a part of the DC Extended Universe. "As of right now we have no connective tissue to those worlds," Berlanti said. "It'd be a separate thing."
That last line -- that it's separate -- is the key thing. It's almost certainly going to be a true, standalone movie in the vein of what DC is doing with Powerless so that the show can have as much leeway with the use of characters and DC concepts as they want. Still, you can be separate from the movies and still tie back to Berlanti's own projects -- which is likely how many fans will want to interpret the situation.
Berlanti also added that the idea for a Booster Gold movie came after a Booster Gold television project "never got off the ground."
That project was to be showrun by Berlanti and his Supergirl and The Flash partner, Andrew Kreisberg; it was set up at Syfy as Untitled Booster Gold Project until it fell apart.
The question of Booster Gold joining the Berlantiverse is one that's been hanging over the character since the show was in development at Syfy, but when DC's Legends of Tomorrow came to The CW, fans doubled down on the speculation.
Legends lead Rip Hunter, after all, is in the comics both the mentor and the son of Booster Gold (not that the current version of Booster knows anything about that yet. But we'll get into the paradoxical nature of Booster stories another time).
It was around this time last year that ComicBook.com speculated as to whether Booster might somehow unite the TV and movie universes, given his role in the comics as protector of DC's Multiverse.
That was driven in part by the now-proven-false assumption that Booster Gold was going to be part of the DC Extended Universe, but the other elements of it -- Berlanti's involvement and Booster's unique role in DC's multiverse -- have remained constant since.
A connection between Booster Gold and Rip Hunter, played through Booster Gold and Legends of Tomorrow, could easily be kept from most or all of the other characters, excepting perhaps The Flash, who is pretty involved with multiverse travel.
After all, it was Booster and Rip who discovered the post-Crisis on Infinite Earths DC Multiverse in the event series 52 -- and then for all intents and purposes didn't share that information with anyone until Flashpoint. So it isn't as though just establishing "Yeah, these guys are aware that one another exist out there somewhere in the multiverse" implies that Booster will be spending time making guest appearances on Legends and telling Team Arrow about his meeting with Superman.
What it would do, and what Warner Bros./DC might be open to, is creating the possibility for such a thing to happen down the line.
