(Reuters) - It already set a record for the largest debut for an animated film last weekend.

Now, for a second weekend in a row, Finding Nemo sequel Finding Dory swam past its competition and collected some US$73.2 million (S$99.5 million) in ticket sales.

That's a big catch for the film, whose gross global ticket sales have hit some US$400 million.

Never a dull moment at the box office, sci-fi film Independence Day: Resurgence rocketed into second with some US$41.6 million in sales.

But it was a bomb with moviegoers, who gave the film a grim 33 per cent score on Rotten Tomatoes.

The film also fell short of its predicted opening weekend goal, which fans say could do with actor Will Smith not reprising his role in the franchise.

Third this weekend, but not sinking to the bottom, was a favorite among comedy fans last weekend as well.

Action-comedy Central Intelligence starring Kevin Hart and Dwayne Johnson kept theatres busy with $18.3 million in sales.

That's around half of what it made when it opened last weekend.
