A fan on YouTube has recreated the extended trailer for Avengers: Age of Ultron shown last night during Marvel's Agents of S.H.I.E.L.D. -- with Lego.
The user who put this together has a bunch of other cool (and often comics-themed) Lego projects, so check them out at his YouTube Channel.
You can check out the Age of Ultron trailer below.
Avengers: Age of Ultron will be in theaters in May.
