Godzilla!, often called Cozzilla, for its director Luigi Cozzi, was a 1977 colorized version of the 1954 film Gojira. It is only available for home ownership through TV recordings and bootleg DVD's based on the old recordings. No versions include the ending, although it has surfaced on Youtube, and the "full" version that surfaced on Youtube in 2014 was a very low quality recording, that had the text from the end of the reel included in the movie, as it hadn't been run properly.
There are rumors that a high quality 8mm print surfaced in recent years, but it was never released, and the movie has never had a proper release on DVD or Bluray. An old introduction used on TV shows some very high quality footage, where the colors are actually quite distinct, while most versions of the movie available are quite faded and poorly aged.The movie spliced in footage from other sources, which is fairly effective at some points but makes it look messy at others. Most of the footage is from The Beast from 20,000 Fathoms and Godzilla, King of the Monsters. There is also at least one scene from Godzilla Raids Again (1955), as well as footage from the wars (which does result in actual human death on screen). The base movie does seem to be from King of the Monsters, although there is added footage from Gojira.
It is unlikely the movie will ever receive a restored release, since Toho studios have never mentioned it at any point, and it's unknown if the current owners will release it.
It is also notable that side B of the original soundtrack to the movie hasn't been released on CD, although does exist on the rare EP.
