WHY?!?

Why do they insist on renaming titles for the Australian release?
In Australia this is called Mayhem. I thought that was strange when I was watching it because I just didn’t think the title suited the movie.
I tried looking for it on IMDB but it took a while because, silly me, I typed the Australian title. Why do they do this? It’s not like Australians wouldn’t understand the title “Suspended Animation”. I know exactly what that means and I think it is a much better title than “Mayhem”

Sorry about my little rant there but if anyone knows why they do this please let me know.
