The box office milestones keep rolling in for “Guardians of the Galaxy.”

After crossing the $200 million mark at the box office last week, the blockbuster is now the top domestic film of the summer. Disney-Marvel’s tentpole had earned $239 million by Friday and is set to gross an estimated $246 million by Saturday, which would top “Transformers: Age of Extinction’s” expected $243.3 million domestic haul.

In fact, the intergalactic actioner will likely soar to no. 1 at the box office, overtaking YA tearjerker “If I Stay” on Sunday, after playing second fiddle to “Teenage Mutant Ninja Turtles” at the box office for two consecutive weekends. “Guardians” stands to earn $252 million by weekend’s end.

Disney’s “Maleficent” fell to third on Friday with $237 million at the domestic box office, followed by two Fox titles: “X-Men: Days of Future Past” has earned $232.6 million and “Dawn of the Planet of the Apes” has accumulated $203.2 million.

However, Paramount’s “Transformers: Age of Extinction” is the worldwide winner by a long-shot, having hauled $1.05 billion by Friday. The fourth pic in Michael Bay’s growing franchise is the only movie to cross $1 billion this year. The sequel has earned over 75% its revenue overseas.

“Guardians” has reeled in $435.5 million worldwide to date. The sci-fi adventure about a rag-tag group of heroes, which cost $170 million to produce, opened to a higher-than-anticipated $94.3 million (crushing the record for August’s top debut) at the beginning of August. Since then, the pic has continued to surprise week after week.

The film is directed by James Gunn and stars Chris Pratt, Zoe Saldana, Dave Bautista, Bradley Cooper (the voice of Rocket) and Vin Diesel (the voice of Groot). “Guardians 2” has already been slated for July 28, 2017.
