Custom Page Specific Widget

Problem:
On my custom created video game, movie, and tv show pages I want to be able to have a sidebar widget which will display content specific to that page’s subject.

Explanation:
I am creating a video game/movie/tv show website for news and reviews. I am using the Custom Pages plugin to create specific pages for individual titles. I’m looking for an additional plugin I can install that will allow me to put a widget in the sidebar which will show some info specific to that title.
For example: When I create the video game page for Mass Effect 3, I would like the widget at the top of the side bar to display the cover for that game as well as a rating for the game. I would like to do the same for every game, movie, and tv show page I create. And I would like this to only appear on the pages associate with that title. I do not want to see this widget on the home page.

Request:
If anyone knows of a plugin or any other way of achieving this effect please let me know.
