E Just days after the January 4 premiere (首映) of Hollywood blockbuster Avatar in China, the box offices across the country had gone beyond 100 million yuan (around $14.7 million), thanks to the enthusiasm of huge number of Chinese movie fans. China Film Group Corp. Estimates are that the total box office may finally reach 500 million yuan. Though almost every movie theater in big cities like Beijing and Shanghai gives Avatar top billing（最优先的档期）, with as many as 20 show times a day, Chinese audience still find it tough to get a ticket. In Beijing, the Wanda Movie Theater in Shijingshan, the first IMAX theater in Asia, is the first choice for Avatar moviegoers. The theater shows the 3D IMAX version of Avatar five times a day, and tickets are generally sold out a day in advance. In Shanghai, to get an IMAX ticket for Avatar can mean waiting in freezing weather all night for a show three days later. Shanghai local media reported that on Friday, around 500 people were queuing for tickets at 8 a.m. in front of the downtown Peace Cinema, including some who had waited for 12 hours. Movie fans came equipped with quilts, wooden stools and snacks, in a scene reminding of that at train ticket windows before the New Year, when huge numbers of Chinese travel to be with family. For the 3D version of Avatar, ticket prices varied for different theaters and time slots(场次), ranging from 60 yuan to 120 yuan. Meanwhile, illegal tickets traders asked as much as 600 yuan for the IMAX version in Shanghai. The Peace Cinema is planning to raise the ticket price for the IMAX version to as much as 200 yuan from the current 150 yuan from Jan. 14 for some time slots. A report by the People's Daily owes the difficulty in getting tickets partly to the lack of 3D screens in China. There are only 11 IMAX commercial theaters in nine cities across China. Because of this, people are traveling long distances to see the movie. In southern China, the IMAX-equipped Dongguan Wanda theater has seen a huge coming of people from Guangzhou and Shenzhen. Wednesday afternoon, due to a technical breakdown of the system, the movie was stopped for an hour, and the sound didn't come together with the picture. In the end, the general manager of the theater had to beg forgiveness on his knees twice to lessen the angry audience who drove a long way to see the movie. The theater had to pay back each audience member the full ticket price as well as 200 yuan for traffic expenses. The world-wide gross（总收入） for "Avatar" is now at $1.335 billion, second only to the $1.843 billion pulled in by "Titanic," another film directed by Cameron. But how long will 'Avatar' manage to hold its death grip around the number one spot? 57. The behavior of movie fans in Shanghai shows that __________.
