How badly will Harry Potter clobber George Clooney this fall? That's the question all of Hollywood is asking themselves now that 20th Century Fox has moved up the release of Clooney's sci-fi thriller, Solaris, from Dec. 13 to Nov. 27 — just a stone's throw from the Nov. 15 debut of Harry Potter and the Chamber of Secrets. Fox is betting that Solaris — which reunites Clooney with his Ocean's Eleven and Out of Sight director Steven Soderbergh — will be the perfect adult alternative to Potter. We're betting Fox will face an uphill battle.
