It's only a matter of days since The Tomorrow War began streaming, and director Chris McKay is already teasing fans with talk of a sequel. Watch the trailer below:
The sci-fi movie landed on Amazon Prime on 2 July, and has since managed to notch an audience score of 82 percent over on review aggregator site Rotten Tomatoes - not bad going.
It looks as though fans' enthusiasm could pay off as well, because director Chris McKay has been dreaming up plans for a follow-up that delves even deeper into the world of the movie's sinister alien 'whitespikes'.
When asked about the possibility of a sequel, 47-year-old McKay told Variety: "We had such a fun design process.
"We talked about the world of these creatures, where they came from, how they were created or raised, and how they were maybe being used.
"I like world-building experiments, especially when you have the potential of some kind of time travel.
"I think that a sequel could go in a lot of fun areas and the ethnographic study of the whitespikes in their world and where they came from, and what their purpose was, and all of that kind of thing.
"So yeah, I think that could be a lot of fun. And with this cast, too, we're just getting started."
The Tomorrow War sees biology teacher - and, conveniently, former Green Beret - Dan Forester confronted by soldiers from the year 2051, who warn him that Earth faces an extinction-level threat from alien invaders called whitespikes.
Before long, Dan (played by Chris Pratt) is one of a motley crew of soldiers and civilians sent hurtling through time to combat the alien army in the future. Gnarly.
Pratt has also spoken about the film, telling Sky News' Backstage podcast: "I think the very best films in this type of genre are rooted in strong family relationships.
"This film does focus on this character, Dan, and yes, he's a soldier and he gets pulled into the future to fight in this war.
"But really important are the relationships he builds and the relationships he has in his life - him being the father to a daughter, or the son to his own father."
He went on to explain that drama is what he looks for in a role, saying: "I think that's really important, it's something that I definitely look for.
"It doesn't matter what it is, if it's a comedy, remove the jokes - what's the drama? If it's an action film, remove the action - what's the drama?
"I think that to me is really important, and that's where the story lies.
"It's the skeleton on which you hang the meat of spectacle or amazing aliens or cool guns or great sci-fi tropes - that skeleton needs to be there."
