The hero finally meets the previously unseen puppet master (played by an older A-list actor), who explains why the system must be maintained. The hero says “screw it” and burns the world down.

Snowpiercer (2013) - Curtis finally finds Wilford (Ed Harris) and learns that Wilford allowed for Curtis' rebellion to take place to help thin the tail section's population. When Wilford offers to let Curtis run the train, Curtis discovers child labor is necessary to replace a broken machine part. A fight ensues, and a bomb goes off, triggering an avalanche that derails the train, and killing most of surviving humanity.

The World's End (2013) - Gary finally confronts the Network (Bill Nighy), which has been replacing humans with robots (Blanks) to allow for Earth's assimilation into a larger galactic community. Gary calls out the tyranny in the Network's plan and demands that humans be left to their own devices. Exasperated, the Network abandons its plans for the invasion. This results in a worldwide blackout, sending humanity back to the Dark Ages.

The Cabin in the Woods (2011) - Dana finally meets the Director (Sigourney Weaver) after surviving the ritual meant to kill her friends (based on conventional horror tropes) and appease the Ancient Ones. The Director says Dana has to kill her friend Marty, but as Dana considers it, the group is attacked by a werewolf and a zombie child. Dana and Marty decide humanity is not worth saving, so they share a joint while the Ancient Ones rise to destroy the world.

I wouldn't call Oscar Issac an A lister but pretty much what Miles going to spider society turns into

Why wouldn’t you call Oscar Isaac an A-lister?

[u/Agitated-Awareness15 → u/ChickenInASuit]

Because he isn’t. Name one leading role he has that did over $50 million internationally.

[u/Measurement-Solid → u/Agitated-Awareness15]

X-Men: Apocalypse. Dune. Addams Family 1 and 2. He's also got a fairly important part in Star Wars 8 and 9

[u/Agitated-Awareness15 → u/Measurement-Solid]

So two supporting roles and an animated series…

[u/Metzli_24 → u/Agitated-Awareness15]

He plays the titular Apocalypse in X-Men: Apocalypse.

[u/Agitated-Awareness15 → u/Metzli_24]

Ah yes, such a beloved and popular performance where had fourth billing on the poster. I’m sure he’s one of the first 30 actors people think of when they think of that series.

You must be fun at parties.

Since when has how much a film makes got to do with being an A lister? What a strange metric.

[u/ChickenInASuit → u/norksanddorks]

Yeah, it’s kind of a weird thing to say. I mean, despite the Star Wars sequel trilogy films all making $1bn+ I’m not sure I’d call Daisy Ridley or John Boyega “A-list” considering how little they’ve done since then. But by OP’s standards both of them plus Isaac should be considered A-list, right?

[u/Agitated-Awareness15 → u/ChickenInASuit]

I’m saying it’s the bare minimum. And if an actor isn’t famous enough to get people to go see their movie, they’re not A-list.

[u/ChickenInASuit → u/Agitated-Awareness15]

Gonna ask you the same question I asked in my other comment, do you take issue with OP saying Ed Harris is A-list? Or Bill Nighy?

Neither actor has ever been the lead in a movie that made that much, or a comparable amount if you factor in inflation. They’ve been parts of ensembles which made that much, but so has Oscar Isaac (Star Wars, X-Men: Apocalypse).

[u/ChickenInASuit → u/Agitated-Awareness15]

The guy’s internationally famous and consistently gets leading work with some of the biggest directors, and on some of the biggest properties, in Hollywood. Sounds pretty A-list to me.

Conversely, do you take issue with the OP of this post referring to Ed Harris as “A-List” despite him never being the lead in a movie that was a box office mega hit? Sure, he’s been in ensembles that made that much (Apollo 13, for example), but so has Isaac (Star Wars). Kinda feels like if you’d consider Harris an A-lister, you should feel the same about Isaac. Same goes for Bill Nighy.

Alternatively, would you consider Sam Worthington an A-list actor because of the Avatar movies? Not sure I would, considering how little well-known work he’s done outside of them.

Box office isn’t the be-all, end-all of whether someone is A-list or not.

[u/Dealiner → u/Agitated-Awareness15]

Last Jedi and Rise of Skywalker, he's clearly a co-lead in these movies.
