It actually looks like the Flashpoint movie might follow the original storyline, especially if this latest rumour is to be believed. According to Forbes, Gal Gadot will appear as Diana Prince aka. Wonder Woman in the recently announced Flashpoint movie.
Fans of the comic-book storyline will know that Flashpoint includes a large number of DC heroes, including Wonder Woman, Batman, Aquaman, Cyborg and of course, The Flash. The article also states that Flashpoint has been scheduled for a 2020 release, which will come as welcome news for most fans. The Flash has been without a director for a while, so fans will surely be happy to see that the project is finally moving forward, in a positive direction.
This report hasn’t been confirmed by the studio and should be taken as speculation, at least until Gadot’s involvement has been officially announced.
