Principal photography began on June 23, 1980. Filming took place on sets at Elstree Studios Studios, England, and on location in La Rochelle in France, Tunisia in North Africa, and Hawaii. Elstree was chosen because it was well-staffed with artists and technicians who had worked on "Star Wars". On-location shooting cost around $100,000 a day in addition to crew salaries; sets cost an additional $4million. The production could only afford certain equipment for a limited time, including a Panaglide camera stabilizer for smoother shots, and a camera crane for higher angles. Spielberg learned to "like" instead of "love" to avoid using too much time trying to achieve the perfect take. He said, "We didn't do 30 or 40 takes; usually only four... Had I had more time and money, it would have turned out a pretentious movie."
