I saw this and assumed right away it was a follow-up because of the "2" in the title. But turns out that wasn't the case at all.
There's also the classic case of Zombi 2, which of course is due to the fact that Dawn Of The Dead is known as Zombi in Italy, and when that became popular they decided to cash in on the success of it and name a completely unrelated movie Zombi 2. The only similiarity being that they both feature zombies.
