Sorry, but you'd have to play all those levels again, but it's entirely worth it. Look at it like this: First three films you've already done and know where everything is; three new films to explore and have fun in; more mini-kit models; more challenges; and more characters for the best game play possible. I'm just saying, it's a wise choice to purchase. (Wii, PS, PS2, PS3, XBOX; don't buy the DS version, it's really crappy)
