Filming

Leterrier had to direct four units with a broken foot.[10] Filming began on July 9, 2007. Shooting primarily took place in Toronto, because mayor David Miller is a Hulk fan and promised to be very helpful to the crew when closing Yonge Street for four nights in September to shoot the Hulk and Blonsky's clash at 125th Street. Despite messing the street with explosives and overturned burning vehicles, the crew would clean-up within twenty minutes so business could continue as normal each day.[45] The first action sequence shot was the Culver University battle, which was filmed at the University of Toronto and Morningside Park. The filmmakers built a glass wall over a walkway at the University for when the soldiers trap him inside to smoke out the Hulk.[21] There was also shooting in the Financial District.[25] A factory in Hamilton, Ontario, which was due for demolition, was the interior of the Brazilian factory. The site's underground floors were used for Ross' military command center.[45] The crew also shot part of the Hulk and the Abomination's fight on a backlot in Hamilton.[46] Other Canadian locations included CFB Trenton and a glacier in Bella Coola, British Columbia.[25] Afterwards, there was a week-long shoot in New York City and two weeks in Rio de Janeiro.[47] While there, the crew shot at Rocinha, Lapa, Tijuca Forest and Santa Teresa. Filming concluded in November after eighty-eight days of filming.[25]
The Incredible Hulk joined Toronto's Green-Screen initiative, to help cut carbon emissions and waste created during filming.[48] Producer Gale Anne Hurd acknowledged the Hulk, being green, was a popular environmental analogy, and Norton himself was an environmentalist. Hybrid and fuel efficient vehicles were used, with low sulfur diesel as their energy source. The construction department used a sustainably harvested, locally sourced yellow pine instead of lauan for the sets, and also used zero-or low-VOC paint. The wood was generally recycled or given to environmental organizations, and paint cans were handed to waste management. In addition, they used; cloth bags; biodegradable food containers; china and silverware food utensils; a stainless steel mug for each production crew member; a contractor who removed bins; recycled paper; biodegradable soap and cleaners in the trailers and production offices; and the sound department used rechargeable batteries.[25] The Incredible Hulk became the first blockbuster film to receive the Environmental Media Association's Green Seal, which is displayed during the end credits.[49]
