Superman Action Comics #775 is considered by many to be the best Superman single issue ever.
A little video from Ifanboy explaining why can be found here.
I bring up this comic because it is the source material for the newest DC animated flick titled “Superman vs. The Elite.” Here’s a trailer.
This was a fun adaptation by original comic writer Joe Kelley. It’s right up there with the best of DC animation and really makes you think about what makes Superman cool.
You can check it out at the SLCPL here.
Also you can find the original comic issue in the collection Justice League Elite vol. 1 which is available for checkout here.
