A studio insider at 20th Century Fox reportedly treats rumor that Buffy creator Joss Whedon is directing X-Men 3 as fact. "Joss Whedon's doing X-Men next year of course...," the source told Moviehole.
That would certainly please the majority of fans who responded to a recent poll of who should replace Bryan Singer (who left to direct Superman). Whedon is currently writing Marvel Comics' Astoshing X-Men series.
Regarding casting, Halle Berry as Storm is still uncertain, the source said. "They're working on that." However, Hugh Jackman (Wolverine) is reportedly back on board as is Famke Janssen (Jean Grey) who has much more to do this time around, the insider said.
