SEVERAL YEARS ago, I raised a question to “Thor” co-creator Stan Lee. Some in Hollywood were already predicting that superhero-film fatigue was about to set in among viewers. Did the Marvel mastermind think that was about to befall the Spandexed set?

“As long as you have a good story, people will come,” Lee told me, noting that “today’s special effects” were just icing on the cake.

As superhero films show no signs of flagging soon, obviously fans are still buying into the Avenger stories — especially as Thor gets his second wind.

Disney/Marvel’s “Thor: The Dark World” not only has won the domestic box office for the second straight weekend, grossing $38.5-million, according to studio estimates Sunday. The sequel has also now already outgained the 2011 original by reaching $479.8-million worldwide; “Thor” topped out at nearly $450-million globally.

“Thor” 2 continues to perform well in many foreign markets; less than one-third of “The Dark World’s” gross — $147-million — is from domestic theaters.

“The Dark World,” in fact, isn’t far behind the still-going-strong “Gravity.” The 3D space drama has now topped $500-million worldwide — $240-million of that from domestic markets.

Also performing well this weekend was the debut of “The Best Man Holiday”: the Universal sequel grossed $30.6-million domestically to finish only behind the tireless Thor.

(Next weekend: “The Hunger Games: Catching Fire” is poised to dominate the box office.)

THE TOP 10: Estimated ticket sales Friday through Sunday at U.S. and Canadian theaters, according to Rentrak:

1. “Thor: The Dark World,” $38.5 million; 2. “The Best Man Holiday,” $30.6 million; 3. “Last Vegas,” $8.9 million; 4. “Free Birds,” $8.3 million; 5. “Jackass Presents: Bad Grandpa,” $7.7 million; 6. “Gravity,” $6.3 million; 7. “Ender’s Game,” $6.2 million; 8. “12 Years a Slave,” $4.7 million; 9. “Captain Phillips,” $4.5 million; 10. “About Time,” $3.5 million.
