BEIJING, July 1 -- "Transformers: Age of Extinction," the fourth installment in the robot franchise, earned 630 million yuan (about 101.6 million U.S. dollars) in its opening weekend in the Chinese mainland.

The stunning sum, which is almost equal to its ticket sales in North America, left "The Breakup Guru," a domestic romance, far behind.

The domestic production grossed 154 million yuan in the week ending June 29, according to a China Film News report on Tuesday.

"The Breakup Guru" was closely followed by Angelina Jolie's "Maleficent," a fantasy-adventure that retells the life of Sleeping Beauty, with 103 million yuan.

The latest version of monster flick "Godzilla" took in 47.8 million yuan to come in fourth.

"Edge of Tomorrow," a sci-fi action movie starring Tom Cruise, rounded up the top five list in the week with 20.2 million yuan.
