Write a program to build a small knowledge base about top "N" movies listed at IMDB

This was an interesting problem that I came across with. This problem is like an open book exam and race against time. The problem had to be solved within an allocated amount of time with a technology stack that is limited only to Ruby/Python/Node.js/Perl.

Few googling here and there and with some knowledge about Ruby I was able to solve this problem within an hour.

Problem Statement:

Build a small knowledge base about top "N" movies listed at http://www.imdb.com/chart/top. Each movie should mention the cast written on the individual page of the movie.
Given the name of a cast member, you should be able to return the movies out of the top "N" movies he/she has acted in. "N" will be passed by the user.
The knowledge base should be built during the runtime and stored in a data structure of your choice.
Q1. For example, if N=3, then you should parse the first 3 movies' individual pages from that page (http://www.imdb.com/chart/top) and build the knowledge base of the cast (there are about 15-20 on every page). Upon querying for "Morgan Freeman", you should return "The Shawshank Redemption". Do not use any external api for this.
Use only Ruby/Python/Node.js/Perl.
