Answer 1

I'm using FbGraph from ( github.com/nov/fb_graph ) Version: 2.7.8 and I'm able to make a batch request for 100 users, at a time and get following information about them by default. I'm not using any access token. So you might be able to get more information including movies.

• id
• name
• first_name
• last_name
• link
• username
• gender
• locale

Here's the demonstration code where ids is an array of Facebook User Ids:

 r = FbGraph::User.fetch("?ids=#{ids.join(",")}")
 r.raw_attributes  #information about the users hashed by their id (String)
