Yes, every scene in the movie can actually be re-created with real Legos (though kids may be sorely disappointed when the Legos don't move on their own as the do in the flick), and Lego and Warner Brothers could have easily made this into a 90-minute ad for the building sets, but there's a real message in the film that goes beyond buying the newest 1,200-piece set and constructing a fighter jet according to the directions.
The film is filled with "cross contamination" where characters and pieces from various sets are integrated and are actually used to help reach the goal. In fact, when the characters try to stick to their original sets/eras, they fail at their missions. Through a twist at the end (I won't reveal it, but it is one directed to the parents in the audience), the message really comes home: Legos are meant for original play, not box play, and the company wants you to mix them up and play with them together.
