Walt Disney and Marvel's "Guardians of the Galaxy" started scoring $11.2 million in late-night shows on July 31, Thursday.
Including $11.2 million worth of Thursday previews and $26.6 million on Aug. 1, Friday, the film earned $37.8 million on its opening weekend.
This shows a possibility for "Guardians of the Galaxy" to earn approximately $100 million, which can make a record not only as the biggest opening weekend of 2014 but also as the highest-earning August opening in history.
Most Marvel films earn 2.5 times their opening earnings for their debut weekends, according to Deadline.
"Guardians of the Galaxy" is then expected to earn at least 2.4 times its $37.8 opening for the weekend, which yields to $91 million, if not 2.65 times yielding to about $100 million, according to Forbes.
The records are currently held by Michael Bay's film "Transformers: Age of Extinction" starring Mark Wahlberg, Nicola Peltz and Jack Reynor earning $100 million in its opening weekend in June, and by Paul Greengrass' 2007 film "The Bourne Ultimatum" starring Matt Damon, Edgar Ramirez and Joan Allen, which earned $69.3 in its August opening.
For 2014's biggest opening weekend record, "Guardians of the Galaxy" also has to beat "Captain America: The Winter Soldier," which earned $95 million in its opening weekend in April.
Distributed by Walt Disney Studios Motion Pictures, "Guardians of the Galaxy" is based on the Marvel Comics superhero team of the same name and produced by Marvel Studios.
"Scooby-Doo" and 'Scooby-Doo 2: Monsters Unleashed" director James Gunn directed the film, which stars Chris Pratt as Peter Quill, Zoe Saldana as Gamora and Dave Bautista as Drax with Vin Diesel and Bradley Cooper for the voices of Groot and Rocket respectively.
On Aug. 1, Friday, "Guardians of the Galaxy" topped the box-office beating "Lucy" with $5.5 million, "Get On Up" with $5 million, "Hercules" with $3.2 million and "Dawn of the Planet of the Apes" with 2.4 million, Entertainment Weekly reported.
