Green Lantern scribe Michael Goldenberg will write the script, according to a report in Variety.
Prior to his co-writing role on the Ryan Reynolds-starring adaptation, Goldenberg wrote the script for Harry Potter and the Order of the Phoenix.
He has reportedly signed on to write the sequel to Green Lantern, although the film has not yet been greenlit.
It was revealed last week that a major DC superhero will be outed as gay in an upcoming issue of DC's new Earth Two series.
