Supergirl Trailer: 25 Easter Eggs And References You Need To See

16. Superman II Alley Scene

Running down an alley is a real Superman trope, and even Sam Raimi referenced it in Spider-Man. It's a moment which has been used in the comic books by the Man of Steel and any number of heroes over the years, so it's perhaps no real surprise that it shows up in Supergirl too (just minus the change into costume). Of course, perhaps one of the most famous examples - and possibly where it originated - is in Richard Lester's Superman II.
