Hi, totally new to API's and programming in general here, so apologies in advance for my simplistic questions!

I'm trying to grab a large amount of movies with their cast with a single request;

I do not think it's possible with just one Request.

however, '&append_to_response=credits' only seems to work if you search for a specific movie id as opposed to using discover,

Right

so I can only grab one movie and its cast at a time.

Right

Is there a better way of doing this?

I think not.
But, perhaps, someone might suggest an easier way.
Maybe Travis Bell can help.

Hi @satyasinha94@gmail.com ,

No, this is the only way. There is no bulk get method. I have an open ticket to think about this here.
