This weekend could see a serious battle for #1 as three brand new releases hit theaters, all of which could deliver as much as $20 million if not more. Among those films is Lionsgate's Rambo: Last Blood, Focus's Downton Abbey and Fox's Ad Astra, all set to target three different audiences and all but Rambo receiving a strong critical response. Which title will have the legs to cross the finish line first?

We'll begin this weekend's preview with Downton Abbey, which will launch in 3,079 locations and Focus is heading into the film's opening with expectations for a $20 million debut. We've been looking at comps such as 2014's The Monuments Men ($22m opening) and Wonder ($27.5m opening) and it's right in line when comparing IMDb page view data over the two weeks leading up to release. It's also outpacing First Man, which opened last October with $16 million when looking at IMDb page view data. We're going out with a $22 million forecast for this weekend, expecting a #1 finish and should it hold, it will be only the third time Focus has had a film open over $20 million with an eye to become the studio's largest opening ever.

In second we're looking for Lionsgate and Millennium's Rambo: Last Blood, which will launch in over 3,600 theaters with the studio anticipating a performance anywhere from $17-20 million, pointing to 2008's Rambo, which opened with $18.2 million. Looking at IMDb page view performance for films such as The Hitman's Bodyguard and London Has Fallen, both of which opened with over $21 million, Last Blood holds a slight edge over both heading into the weekend. It's also outpacing Angel Has Fallen, which also debuted over $21 million just a few weeks ago. While this helps suggest the film could easily reach $21 million, if not higher, the $18 million opening for the last film does cause us to hesitate ever so slightly, keeping expectations right around $20 million, knowing full well it could end up +/- $2 million or more on either side of that number. That being said, that difference could end up being the difference between a first place finish or perhaps slipping as far down as fifth.

WB and New Line's It: Chapter Two is looking at a drop around -52% after holding on better than expected last weekend. Should that forecast hold we're looking at a $19 million weekend and a domestic cume topping $180 million by end of day Sunday.

Right behind it, or perhaps climbing even higher on the list is Disney's release of Fox's Ad Astra. Starring Brad Pitt, the sci-fi feature is debuting in 3,460 theaters with tracking suggesting a debut in the high-teens. We're sticking to that forecast in our projections for this weekend, going out with an $19 million forecast, but we've seen plenty of evidence this could go much higher.

A peek at IMDb page views shows Ad Astra pacing similarly to films such as Arrival ($24 million opening) and out pacing Passengers ($14.8 million opening), both signals suggesting a performance anywhere from $19-25 million is not at all unlikely, and perhaps even more when you consider Arrival opened in 1,143 fewer locations. That said, IMDb page view data also shows the film outpacing features such as Gravity, Elysium and Oblivion ahead of release. How much of this interest is driven merely by curiosity is tough to say, but we can't discount the fact interest does seem to be increasing, making this one of the more compelling titles to watch heading into the weekend.

Rounding out the top five we have STXfilms's Hustlers, which had an impressive debut last weekend, giving the studio a record opening weekend with $33.1 million, topping the opening weekend of films such as Girls Trip and Bad Moms. While the film also worked for critics, the only thing heading into this second weekend that's a little concerning is the "B-" CinemaScore from opening day audiences. By comparison, Bad Moms received an "A" and Girls Trip an "A+". So what does that mean for this weekend? Had that CinemaScore been in the "A" range we might have been looking at a -40% drop if not even better, but as it is we're looking more around -47% and a $17.6 million second weekend, which would push the film's domestic cume around $63 million by the end of the weekend, making it the fourth largest release all-time from STX after just ten days in release.

In limited release, Fox International will release The Zoya Factor in 100 theaters and Sony Classics will debut Where's My Roy Cohn? in four locations.
