There’s really little relevance to 3-D in this post, other that the trailer presents this re-imagining of The Empire Strikes Back as a 50’s 3-D film. Many of the clips used go back into the 40’s and even 30’s. In many ways this is less of a parody of the second film in the Star Wars series (oh yah, it’s now considered the 5th film in the franchise), and more of a look at what surely influenced Lucas when he dreamed up the original Star Wars concept.
Either way it’s a fun little bit of nonsense.
