Compared are the cut US DVD by Global Multimedia (PG-13) and the uncut US DVD by Westlake Entertainment (R-Rated).

Difference: 4 scenes with a total length of 58 seconds.

After the impact of a meteor, respectable retiree Max Page is controlled by some alien force. Under its influence, he develops a lethal desire for human blood. Max commits a series of murders and runs. FBI Agent John Mills is chasing him but it turns out to be more difficult than he originally expected. Every time Max gets fresh blood, his body gets younger which makes it almost impossible to ID him. (Hell on Earth)

The Arrival is a rather bad flick but at least it has John Saxon in it. So far, the only uncut release is the US DVD. However, the German release only lacks a few plot scenes which is why using it to make this comparison was not a problem. Anyway, there is also a cut PG-13 DVD in the US - released as "The Unwelcomed" - and it lacks some nudity and love scenes. Furthermore, every single F-bomb in the entire movie got deleted from the audio track.
