Geek showbiz news has been mounting in the past few days and we round it up here.

Bad Robot and Warner Bros. Television are developing a Madame Xanadu one-hour drama series for HBO Max, according to Variety.  Angela Robinson (True Blood) is writing and will executive produce with J.J. Abrams and Ben Stephenson if the show goes forward.  The immortal fortune teller and sorceress created by David Michelinie, Val Mayerik, and Michael William Kaluta in 1978 was introduced to television in the DC Universe Swamp Thing series (see "’Swamp Thing’ Finds Its Madame Xanadu").

The release date for Dune has been moved back three weeks to October 22, according to The Hollywood Reporter.  That puts the film two weeks after James Bond: No Time to Die and two weeks before Eternals in a blockbuster-heavy Fall (see "Best in Shows – 2021").
