Yes, I have seen this. :)
It's a very clever and funny (but not cheesy) trailer for a LEGO Movie produced by Warner Bros., slated to be released next year. Among the stars featured in it are Chris Pratt, Elizabeth Banks, Morgan Freeman, Will Ferrell, and more.
LEGO just got legit.
P.S. Yes, I did get all 7 HF summer 2013 sets. Still saving up to get the Chima sets.
P.P.S. Yes, I know that I haven't posted MOCs in a while. New ones will be up soon.
