Click the Documents tab and in that window click the Cast field to expand it. Maybe it will make more sense.

A movie has one or more casts.

Hi @007_jb, thanks for your contribution :slight_smile:

Hi @Shrey_46820,

This means the cast field in the video.movies collection has more than one value and they are stored in an array.

For instance this is what it could look like :

{
"Cast":["Claudia Cardinale","Henry Fonda","Jason Robards","Charles Bronson"]
...
}

Hope it helps!

If you have any other issue, please feel free to get back to us.

Happy Learning :slight_smile:
