It’s going to be a very crowded weekend at the box office.IT Chapter Twohas had a clear path to dominance over the past couple of weeks, with the horror sequel raking in $39.6 million for a second straight win last weekend. However, a trio of new arrivals is going to see things get shaken up in a big way. Lionsgate is releasingRambo: Last Blood, 20th Century Fox is releasingAd Astraand Focus Features is behind theDownton Abbeymovie. The question is, who will come out on top?

This isn’t as cut and dry as it is some weeks. All three of the weekend’sbox officenewcomers are expected to debut in the $20 million range, andIT Chapter Twowill be right in that ballpark as well. To make matters a tiny bit more complicated,Hustlerswon’t be too far behind. Not to mention that the movie has earned rave reviews and is generating excellent word of mouth thus far, which means it could easily over-perform in its second frame. Point being, it could be a very right race all across the top five.

Vegas odds are likely onRambo: Last Blood. Box office tracking has the sequel, which once again stars Sylvester Stallone as John Rambo, earning between $20 and $24 million. But Lionsgate has put a hefty marketing campaign behind this one and the fact that the character has been away for a while could work to its benefit. Meanwhile,Ad Astra, a high-concept sci-fi flick starring Brad Pitt from director James Gray, should be right at or near the $20 million mark. The movie has earned rave reviews, but the heady nature of the material may prevent it from having the mass appeal of something like Christopher Nolan’sInterstellar. Considering the $80 million production budget, that may not cut it.

Rounding out the top five will beDownton Abbey, the big screen continuation of the beloved TV series, andHustlers, the heralded stripper drama starring Jennifer Lopez and Constance Wu. While some analysts believeDownton Abbey, directed by Michael Engler, will get closer to $20 million, in part thanks to tremendous presales, other analysts believe this one is going to be very heavily front-loaded with pre-sales. As such, it could wind up closer to $15 or $16 million

Hustlers, on the other hand, did better than expected with $33.1 million last weekend and is now generating legitimate Oscar buzz. With an 88 percent score on Rotten Tomatoes, the flick should see, at most, a 50 percent drop, which could put it just aboveDownton Abbey. In almost every case, each studio comes out a winner here.Ad Astrais the exception, as Disney is probably going to suffer yet another lackluster performance from a Fox title they inherited in the merger.
