This broke my brain, I identified it as “The Mist” but I was 100% sure Mark Wahlberg was the main character so I was trying to work out what the joke was/why Wahlberg was replaced.

Guess I have my own Berenstein Bears thing going on.

He’s the main character in The Happening. Similar premise except its a plague that causes people to commit suicide

Ah good call, released within a year of each other, I’m probably merging the two in my head to some extent.

You’ve also got the more recent one with Sandra Bullock, where the monsters only attack people who look at them. Except they’re invisible.

And there’s mist everywhere at the beginning I think

Bird Box?
