On Warner Home Video’s release of “Justice League: Season One” you can also find a cool hidden feature if you know where to look for it.
From the Main Menu go to the “Special Features” section and highlight the menu entry that is in the center of the page. Then, press the “Left” arrow key on your remote control to highlight Green Lantern’s chest emblem. Now press the “Enter” key on your remote control and you will get to see a small feature with Bruce Timm introducing and then showing a music-only animation clip showcasing the Blackhawks Squadron from the “Savage Time” episode in which they first appeared. This clip, as Timm explains, was first shown at a Comic Con some time back.
