"Transformers: Age of Extinction," the fourth installment in the robot movie franchise, earned 756 million yuan (about 121.9 million U.S. dollars) on the Chinese mainland in the week ending July 6.

The latest installment, whose box office earnings had hit 1.386 billion yuan by last week, has bypassed the record set by "Avatar" to become the all-time top-grossing film on the Chinese mainland.

The towering transformers were followed by "The Breakup Guru," a domestic romance that grossed a respectable 255 million yuan in the week, according to a China Film News report on Wednesday.

Third place went to "Maleficent," a fantasy-adventure starring Angelina Jolie that retells the life of Sleeping Beauty, with 28 million yuan.

The third installment of the horror series "Bunshinsaba" took in 23 million yuan to come in fourth.

"American Hustle," which debuted on July 4, rounded up the top five list in the week with 9.17 million yuan.
