Ivan Guerrero, the videographer behind the 1950s version of The Empire Strikes Back, has created an old-timey preview of Joss Whedon's upcoming Avengers film by splicing together 50+ clips from old scifi movies. Plus, the movie's based on Secret Invasion!

Also, here's the Easter egg-filled annotations reel. It's definitely worth a watch — look out for cameos from Truman-era Dr. Strange, Peter Parker, and Uatu the Watcher.
