An Instagram post gets an unexpected boost. A TikTok catches in the algorithm.

Sometimes that's all it takes to launch someone into internet fame. But then what?

This blue up is a new podcast documentary that reveals how social media

start and is made. It's a different kind of fame. That's not always as glamorous as it looks.

From Spotify and the Ring or Podcast Network, I'm Alyssa Bereznek.

You can listen to this blue up on Spotify or wherever you get your podcasts.

When Sigourney Weaver first heard there would be a sequel to Alien. She didn't want to star in it.

That is until she read the screenplay. Here's how she remembers it.

Every single page was my character, Ripley. Expanded and with all kinds of different levels of drama in it.

Everything about this script was so good and powerful.

Weaver wasn't familiar with the young filmmaker who wrote the script.

But she could tell that his follow-up to Ridley Scott's 1979 sci-fi horror classic was more than just a money grab.

It was a war movie in space.

To the actress, the idea of Ellen Ripley fighting aliens alongside a unit of colonial marines sounded great.

She says that there was only one problem.

First of all, I didn't know there would be machine guns in it and I worked for gun control for a number of years.

And I said, you know, I'm sorry, the gun thing. That's not going to work for me.

Another director might have scoffed at Weaver or even thrown a tantrum to studio execs behind her back.

But not James Cameron. He responded by taking her to a shooting range.

After letting off a few bursts of ammunition, she began to see the world through Cameron's eyes.

That experience gives you so much adrenaline.

It's a little bit transforming, even though I still have very powerful reservations about guns.
