From Anime News Service:
Goo Movie pointed out something interesting regarding the attendance numbers of Paprika at Venice. American actor Ben Afflek's latest film Hollywood Land screened in the same theater on August 31st. Despite the star himself being in attendance, tickets were sold only filling 700 seats. Satoshi Kon's screening on the 2nd drew 1060 people filling it to overcapacity. Tickets sold in out in less than an hour.
As an aside Hochi Shimbun has more on the director's 5 minute standing ovation. Ringing applause, bravos and shouts of joy filled the theater for 5 minutes or more. During this time Satoshi Kon says he recalled faces of his staff, many sitting in front of a computer in a dark room for 2 years during the production. He said he was there as his staff's representative. Feeling excited and rattled he said he also wish his staff could hear the applause for 2 years time.
