I don't recall hearing about anything like this on 3/11 or any other day for that matter...

It's called a "movie trailer". It says so in the comments, too.

Haha...that's a sarcastic laugh.

In light of topic New Change for Conspiracy Theory section: only space and astronomy, what's the connection between the movie ad and a space or astronomy conspiracy?

I don't watch YouTube videos--what's it a movie trailer for?

Judging by the "jumpy" cinematography, I'd say it's for inducing nausea.

And this address Gillianren and Bozola's questions as well...

I think this is supposed to be a movie about a Virus outbreak- supposedly from Space.
So it kinda qualifies as a space conspiracy-if it wasn't a movie trailer anyway
