Like the real trailer, which came out Friday, the Lego recreations open with Iron Man in space, in a ship he probably found on Titan. He's leaving a recorded message for Pepper Potts. "Part of the journey is the end," he laments after his food and water have run out. 

Both Lego versions are faithful to the original trailer, frame by frame.
