Answer 10 consecutive questions correctly in a "Classic" game. 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.
