It starts off as a story of a family trying to start again and trying to protect each other.

Obviously,somethingis in this house and something is troubling all the siblings.

It does kind of take a turn.

It was probably one of the most intense auditions I had to do.

Was the shoot a bonding experience for the actors who were playing siblings?Yeah, completely.

We all still stay in touch.

We were all kind of isolated in our own way in this small town.

It was a very big bonding experience and I feel like that definitely shows on the screen.

We were all there together.

When do you start shooting the third season ofStranger Things?Im going back at the end of April.

So, Im pretty excited to get the scripts and to go back, for sure.
