Tom Cruise thriller’ Valkyrie’ to open Christmas ’08. Tom Cruise thriller’ Valkyrie’ has had its release date moved for a third time. The film, which revolves around a plot by insurgent German soldiers to assassinate Adolf Hitler, will open on December 26th this year. The movie had originally been scheduled for a summer 2008 release. It was later pushed back to October, then again to February 2009. Sources close to events said the move was made for purely commercial reasons, after a screening of the film went well. The studio sees it as a holiday picture and award consideration was not a factor.
