A longtime Hollywood cash cow managed to come on top at the box office this weekend, but with greatly diminished returns when compared to its predecessors.

In first is Transformers: The Last Knight (read our review), which made $45.3 million over the three-day weekend. Since the film came out on Wednesday, June 21, its domestic total so far is $69 million. That is by far the lowest five-day start for this lucrative franchise in the United States, indicating that at least in North America, audiences have started to tire of the Autobots and Decepticons. As has become par for the course for the series, The Last Knight was widely panned by critics, with many people writing it off as being more of the same. Transformers has been on a downward trajectory over the course of the last few installments, so it's clear the interest isn't as high as it once was. Last Knight was also dealing with a strong holdover in Wonder Woman, which was the recipient of strong word-of-mouth since it opened at the beginning of the month.

Since The Last Knight looks to be a non-starter in the U.S., Paramount is going to have to hope for a strong showing internationally. Fortunately for the studio, that looks to be just what they got, as the global total is $265.2 million so far. Transformers 5 is the latest movie to demonstrate the power of the international marketplace, as that figure accounts for the film's massive $217 million production budget. There's obviously still some way to go before it turns a profit, but this is a strong start. Paramount is looking to use The Last Knight as a springboard for various spinoffs and sequels, so they need this film to do solid business over the course of its run.

Falling to second is last week's champ, Cars 3, which brought in $25.1 million. The latest from Pixar is now up to $99.8 million and should start to see its numbers go down a bit with the impending arrival of Despicable Me 3 next weekend.

In third is Wonder Woman with $25.1 million. DC's newest blockbuster continues to hold well, riding high after earning enthusiastic reviews from fans and critics. Its domestic total is currently $318.3 million, and it looks like it's only a matter of time before it becomes the highest-grossing installment in the shared universe to date.

Coming in fourth is 47 Meters Down with $7.4 million in its second weekend. The shark attack film raised its Stateside total to $24.2 million.

Rounding out the top five is All Eyez on Me. The Tupac biopic, which did not generate the best reception upon its release, tumbled 77.9 percent in its second weekend and brought in $5.8 million. Clearly, the negative word-of-mouth didn't do the film any favors, and its overall appeal was greatly limited. It has now made $38.6 million in the U.S.

In sixth is The Mummy with $5.8 million. Universal's kickstart to their Dark Universe has struggled throughout its run and now stands at just $68.5 million domestically.

The #7 film is Pirates of the Caribbean: Dead Men Tell No Tales. Jack Sparrow's fifth adventure grossed $5.2 million in its fifth weekend and has made $160 million in the States.

Coming in eighth is Rough Night. The comedy made $4.7 million over the weekend, increasing its domestic total to $16.6 million.

Captain Underpants: The First Epic Movie is the #9 film with $4.2 million. The animated family film now stands at $65.7 million.

Capping off the top 10 is Guardians of the Galaxy Vol. 2. Marvel's latest hit made $3 million in its eighth weekend to raise its domestic total to $380.2 million.
