Variety‘s Anne Thompson has written a bit more on the Superman Returns sequel:
No screenwriters are on board. “Returns” writers Michael Dougherty and Dan Harris opted out of penning “Superman: Man of Steel,” and the strike arrived just as other scribes were to pitch ideas. Internally, Warners has moved the release date from 2009 to 2010.
After “Superman Returns” delivered a disappointing box office take of $386 million worldwide, Warner Bros. and Singer debated how to proceed with the next “Superman” pic. The studio even considered rebooting the franchise with someone else.
But eventually WB execs Alan Horn and Jeff Robinov agreed to proceed with Singer at the helm of a $170 million “Man of Steel” packed with more action, a super-powered villain and less romantic melodrama. Before Singer started production on UA’s “Valkyrie,” WB and co-financier Legendary Pictures closed a deal for him to produce and direct “Superman: Man of Steel.”
According to a spokesman for the director’s reps at William Morris,” ‘Superman’ is moving forward with Bryan Singer attached.” But inside the studio, “Superman” is not on any fast track, and word is that Singer may wind up not directing it.
The article also again mentions that Justice League might not be going ahead until after the strike.
