It isn't London's recent bomb attacks that cause the release date of the terrorism-themed movie "V for Vendetta" being postponed. Instead, technical difficulties are responsible for the date change from November until next year, the movie bosses insisted.

Aside, a Warner Brothers source explains, "The film is still in post-production and the visual effects wouldn't be completed in time. That's why it's being postponed. There might also be some extra shooting days but none of the scenes involving the Underground are being altered."

"V for Vendetta" stars Natalie Portman and Hugo Weaving against the terrifying backdrop of bombings on the London underground, that the movie is all about and producers won't re-edit the scenes which closely mimic recent murderous events in the city.
