Zack Stentz, writer of Thor and X-Men: First Class as well as a few episodes of The Flash, has apparently started work on Booster Gold for Warner Bros., per a few cryptic tweets he's made in the last day or so.
The first, and most obvious, was posted yesterday and named "today's writing inspiration" as Booster Gold #1 from 1986, the character's first appearance, written and drawn by Dan Jurgens. The issue featured Booster facing off against Blackguard, a B-list DC Comics villain whose most recent appearance was in Jurgens's own Superman: Lois and Clark.
You can see a preview of Booster Gold #1 in the attached image gallery. The issue recently became available digitally for the first time.
Later tweets ruminated on screenwriting basics, from writing good villains to what makes a compelling lead, and might or might not actually have anything (directly) to do with the Booster Gold script.
Booster Gold is Michael Jon Carter, a college athlete from the 25th Century who, after being caught taking bribes, is forced to quit football and take a job as a night janitor at a museum. There, he steals a bunch of high-tech equipment and uses it to travel back in time and make a name for himself as a superhero.
Various different iterations of Booster Gold have tackled his obsession with fame differently: in Booster's first series by writer/artist Dan Jurgens, the character merely wanted to become rich and famous because that's the path he had been on before he lost everything. During the Keith Giffen/J.M. .DeMatteis run on Justice League International, his get-rich-quick schemes took on a decidedly comedic bent, with Booster and his best friend Ted "Blue Beetle" Kord serving as the Laurel and Hardy of the superhero set. Finally, after a soft reboot in 2005, Booster was reinvented as a Time Master, but one who had to allow the world to believe that he's a glory-seeking clod in order to protect his true role: secretly, he guards the timeline from those who would alter it.
Stentz may (or may not) have given some clue as to which version of Booster will star in his screenplay when he tweeted this a few hours ago:

There is no official release date yet for Booster Gold, and no director officially attached. The film will be executive produced by Greg Berlanti, who oversees several of DC's TV shows for The CW (Supergirl, The Flash, Arrow, and DC's Legends of Tomorrow) and FOX (Black Lightning).
