1. Different Companies, Different Rights:
* Toho: The Japanese studio that owns the Godzilla franchise, distributes most of the movies.
* American Distributors: Different studios have distributed American versions of Godzilla movies over the years, often with re-edited content.
* Other Countries: There are also Godzilla movies made in other countries (like the 1998 American "Godzilla" with Matthew Broderick), so it's not always straightforward.
2. "Complete" is subjective:
* Showa Era (1954-1975): This is the classic Godzilla era, and you'll find several comprehensive sets from Toho or Criterion.
* Heisei Era (1984-1995): There are fewer complete sets, but you can find most of these movies individually or in smaller collections.
* Millennium Era (1999-2004): This era is well-represented on Blu-ray and DVD.
* Reiwa Era (2016-present): These movies are readily available from Toho and American distributors.
* Monsterverse (2014-present): These are the American-produced Godzilla movies starring the "Monsterverse" cast (Kong, King Ghidorah, etc.).
3. Finding the "Right" Collection:
* Streaming Services: Platforms like HBO Max and Tubi offer a selection of Godzilla movies, but rarely complete collections.
* Blu-ray/DVD: Many retailers sell individual discs, multi-movie sets, and special edition collections.
* Online Marketplaces: Websites like eBay and Amazon can offer both new and used Godzilla movies.
To get as close to a complete collection as possible, you'll need to do some research and possibly purchase from multiple sources. Be sure to check for region codes and language options if you're buying from outside of the US.
