When going online this morning, I found the following on Reddit:

https://www.reddit.com/r/DC_Cinematic/comments/4ntwgz/the_ultimate_cut_is_available_right_now/

Basically, various people noted that if you pre-purchased a digital copy of the Ultimate Edition of Batman v Superman: Dawn of Justice, it was as of today available for downloading and watching, albeit in SD format, via Flixster or Cinemanow.

I pre-purchased the Ultimate Edition via VUDU but many of the films I buy (not all) are watchable via the Flixster app so I took a look and…nothing.  Then, about ten minutes ago I tried again and, sure enough, I was able to download a SD copy of the Ultimate Edition of the film!

Unfortunately I don’t have the time to see it in its entirety right now but I did watch the first few minutes and can verify this screencap:

Is legitimate.  This is the way the movie’s title is presented.

I’ll offer my full review of the Ultimate Edition soon but, meanwhile, if you have pre-purchased your digital copy of the Ultimate Edition of the film, I can verify you can download it through Flixster.

UPDATE:  It appears WB has stopped this accidental early release of the movie and you can no longer get it as I did.
