Warner Bros.' original plans for The Flash movie would've included Green Lantern showing up at the end of the film. The studio has been trying to get the world's finest heroes onto the big screen for several years now, and they only managed to do with Zack Snyder's Justice League in November 2017. While Superman and Wonder Woman have already received origin stories, the next step is developing solo movies for the rest of the unofficially titled DCEU's superheroes, including The Flash.

Long before the Scarlet Speedster made his way into The CW's Arrowverse, The Flash TV series co-creator Greg Berlanti developed a script with Arrow co-creator Marc Guggenheim for a live-action Flash movie, presumably featuring Ezra Miller in the title role, considering that the actor joined the DCEU as Barry Allen, aka the Flash, in 2014. However, when The LEGO Movie's Phil Lord and Chris Miller turned in their own screenplay for The Flash movie in 2015, the studio seemingly shelved Berlanti and Guggenheim's long in-development story. And while little is known about the Flash's unrealized solo film, a key detail has now surfaced online.

In an interview with Discussing Film at ACE Comic Con 2017, Marc Guggenheim briefly discussed his past film projects in addition to his current television gigs, namely Arrow and DC's Legends of Tomorrow. Guggenheim mentioned that his and Berlanti's script for The Flash movie had Green Lantern show up at the end. He said: "We did a Flash screenplay and Hal Jordan showed up at the end of Flash."

Considering that Berlanti and Guggenheim both co-wrote the original screenplay for Martin Campbell's 2011 Green Lantern film, starring Ryan Reynolds as the eponymous superhero, it's possible that the Hal Jordan that showed up at the end of their Flash movie would've been Reynolds' Lantern. Prior to Warner Bros. launching the DCEU, they initially had plans to build a shared universe off of their much-maligned Green Lantern film. Of course, when that movie flopped at the worldwide box office, the studio changed their plans and used Snyder's Man of Steel as their launchpad.

The Flash movie has gone through numerous changes since Berlanti and Guggenheim presented their draft screenplay in 2013. The studio recently reworked The Flash solo film into a Flashpoint adaptation, potentially starring Ben Affleck's Batman. Since Hal Jordan (and the Green Lanterns) has yet to join the DCEU, it's possible that comic book fans will still see Green Lantern show up at the end of Warners' upcoming Flashpoint movie, which could also lead into their in-development Green Lantern Corps film.
