Hi George,

It would be nice to get featured list and/or popular lists or retrive lists based on a movie.

Yes, this is planned.

Also I was wondering how the credits (specifically cast) are sorted?

I think you're asking about the API, is that right? If so, in the response I make no guarantees of the order but you can use the order field to ensure you sort them locally on your end.

Hi Travis,

"It would be nice to get featured list and/or popular lists or retrive lists based on a movie."

Any word on this?

Thanks.

Hi @pulkit0909,

Still planned and getting higher on my priority list. I definitely think it's important to surface more popular list content, don't worry
