‘Arrow,’ ‘The Flash,’ ‘Supergirl,’ ‘Legends of Tomorrow’ Crossover Spoilers: How Will Oliver Queen, Sara Lance And John Diggle React To Kara Danvers?

Sara Lance (Caity Lotz), John Diggle (David Ramsey) and Oliver Queen (Stephen Amell) will finally meet Kara Danvers (Melissa Benoist) in the highly anticipated four-way crossover between “Arrow,” “The Flash,” “Supergirl” and “Legends of Tomorrow” this TV season. And according to “The Flash” and “Supergirl” executive producer Andrew Kreisberg, the trio will have different reactions when they come face-to-face with the Girl of Steel for the first time.

“I think Sara’s got a little crush on her,” Kreisberg said (via Comicbook.com) during a screening of “Supergirl” Season 2, episode 2. “[John Diggle], as always ... just when he think he’s seen it all, you know? There’s a moment in it where somebody says, ‘This is Supergirl,’ and he’s like, ‘What’s so super about her?’ She just lifts off the ground and Dig’s like, ‘I’m convinced.’”

Oliver, on the other hand, “sort of keeps his distance” from Supergirl, who misinterprets the Green Arrow’s rather cold welcome.

“Part of Oliver’s journey in these episodes is, he’s kind of hit his breaking point with things he’s willing to accept. He’s had Mirakuru soldiers and the Lazarus Pit and magic with Damien Darhk, but flying aliens who can incinerate you with their eyes is beyond the pale for him. So he sort of keeps his distance, which is a very Oliver thing to do,” Kreisberg explained. “He keeps his distance, and Kara comments, ‘Does he not like me?’ And Barry’s [Grant Gustin] like, ‘No, that’s kind of how he treats everybody.’”

“Arrow” and “Legends of Tomorrow” executive producer Marc Guggenheim revealed last month that CW’s DC Comics TV heroes will all team up to defeat the alien race Dominators in the four-way crossover.

“This year, for our mega ‘Arrowverse’ crossover, we’re taking inspiration from a DC crossover from the late 1980s known as ‘Invasion!’ which featured … the Dominators, who’d previously, vexed the Legion of Superheroes,” he said (via Entertainment Weekly). “We’re using cutting edge prosthetics and computer effects to achieve a feature film-quality look which is faithful to ‘Invasion!’ artist Todd McFarlane’s interpretation of the characters.”

Meanwhile, Kevin Smith, who has directed a couple “The Flash” episodes, revealed two weeks ago that seeing the script for the crossover event made him even more excited for the week-long special.

“I’ve seen what they’ve got planned for the massive event, and it f--king RULES!” he wrote on Instagram. “It’s breathtaking in its enormity and will be particularly fun for any long term @dccomics fan like me who has been reading that company’s books for decades. They’re pulling elements from a story that was a favorite of mine back in the day so there are tremendous terms and legendary locations in the crossover script I saw that will make any #dccomics lover fill their Undergoes!”

The four-way crossover will air sometime this fall.
