Although a few scenes have already been filmed, in preparation for the special effects, Franco revealed that principal photography starts next week. He also said that the cast had already done a script reading.
Franco was mum on whether or not Harry will become more villainous in the third film – he simply shrugged his shoulders and smiled.
The movie is expected to film in the New York area from May through September.
Columbia Pictures is targeting a May 4, 2007 release date for Spider-Man 3. Tobey Maguire and Kirsten Dunst are back as well, with Thomas Haden Church on board as Sandman and Topher Grace playing a mysterious role.
