What are the release dates for Cataclysmo and Battle Earth - 2008?

You're likely thinking of "Cataclysm" and "Battle for Earth", but those are not the correct titles for movies from 2008.

Let's clarify:

* Cataclysm is a 2011 film, not 2008.

* Battle for Earth is a 2011 animated film, not 2008.

There are no movies called "Cataclysmo" or "Battle Earth - 2008". It is possible you are remembering the titles incorrectly or there was a misunderstanding.

If you can provide any more context, such as the genre or any other details you remember about the movies, I might be able to assist you further.
