How to unlock the Full Circle achievement in Trivial Pursuit - Definitive Guide

Wedges are earned by correctly answering the question given after landing on a Wedge HQ, the large spaces found at the intersections of the outer ring of spaces and the 'spokes' leading to the game board's 'hub'. Earn each of the game's six wedges to unlock this trophy. If you don't know the answer, press the 
button to pause the game, giving you ample time to look it up. I highly recommend downloading the Trivial Pursuit Movie Pack, which is available free from Playstation Store, and consulting SirkSirk's Movie Pack Questions & Answers thread.
NOTE: If you're unable to find the answer, feel free to guess; quitting to the XMB before the game auto-saves will allow you to try again.
