Moviegoers went back for more of Mel Gibson and his “Signs” this Labor Day weekend, making the movie No. 1 at the box office. The victory was a bit of a surprise, given that the film has been out for several weeks and faced competition from a handful of newer movies.

Still, an even bigger surprise is the sleeper hit, “My Big Fat Greek Wedding,” which after five months in release enjoyed its best weekend yet and came in an impressive second, topping Vin Diesel’s “XXX.”

Overall, this summer was one for the record books. Revenues from Memorial Day weekend through Labor Day were a precedent-setting $3.15 billion, beating last year’s record of $3.06 billion, Paul Dergarabedian, president of box-office tracker Exhibitor Relations, tells the Associated Press. (Although, by factoring in higher ticket prices, admissions were down slightly this summer.)

At the top of the hot-weather heap: “Spider-Man,” which smashed opening-weekend box-office records when it debuted in early May and hit No. 5 on the all-time list (with $404 million domestically), and “Star Wars: Episode II — Attack of the Clones,” which grossed $300 million.

The estimated ticket sales for Friday through Monday were as follows:

1. “Signs,” $16.5 million
2. “My Big Fat Greek Wedding,” $14.6 million
3. “XXX,” $13.1 million
4. “Spy Kids 2: The Island of Lost Dreams,” $7.3 million
5. “fear dot com,” $7.12 million
6. “Austin Powers in Goldmember,” $7.1 million
7. “Blue Crush,” $5.4 million
8. “Serving Sara,” $4.2 million
9. “The Good Girl,” $3.6 million
10. “One Hour Photo,” $3.33 million
