In Australia, "The Avengers" has already banked $7 million, a total that has only been beaten by "Harry Potter and the Deathly Hallows, Part 2," which earned $8 million during its Down Under debut.
The foreign rollout has proven lucrative elsewhere, too, as France added $3 million to the total.
Early tracking estimated that "The Avengers" could make more than $150 million during its early May opening weekend in the U.S. That would put the film in the same class as "Spider-Man 3," "The Hunger Games," "The Dark Knight" and "Deathly Hallows, Part 2."
This could potentially mean the biggest debut for a Marvel Studios movie yet. "Iron Man 2" currently holds that honor. The Robert Downey Jr. sequel opened to $128 million back in 2010. That's followed by the first "Iron Man" at $98 million.
"The Avengers" has the added advantage of higher ticket prices. The film is playing both in 3-D and in IMAX 3-D, so each individual ticket will add more to the final total. "Harry Potter and the Deathly Hallows, Part 2" saw a large bump in its record-breaking run thanks in part to higher prices attached to 3-D showings.
