With Justice League: Season 1 just having been announced on DVD, there is a chance that Season 2 of Justice League being released on DVD in Full Screen, despite it having been animated in Widescreen.

A note from show creator / producer Bruce Timm was posted on the forums concerning this matter:

We'll be starting the special features stuff in the next few weeks, which means a decision on fullscreen or widescreen will need to be made very soon. I've been doing my best to persuade the WHV folks to release the season two set (and all subsequent JLU sets) in widescreen, but it's an uphill battle (fullscreen format is the standard default mode for "family entertainment" DVDs). A deluge of polite, but emphatic, letters expressing fan support for widescreen DVD sets just might tip the scales.

In an effort to inform Warner Bros. Home Video about this issue, the forum members, Toon Zone News, The Watchtower and The World's Finest have started a 'Justice League: Season 2 DVD Widescreen' campaign. The only thing we're asking fans of Justice League to do is write a letter to Warner Home Video, expressing your desire for the second season of Justice League (and for that matter, future releases of Justice League Unlimited) in an 1.85:1 Anamorphic Widescreen release. It's possible that a deluge of concise and polite letters may help their decision on how to proceed with the Aspect Ratio for Season 2 of Justice League.

Listed below is the mailing address for Warner Home Video. It's imperative that these letters get sent out as soon as possible, as production on the second season of Justice League's DVD release will begin within a few weeks.
