This is a comparison between the US/UK Version and the Theatrical Version. Both are included on the German DVD released by Marketing.

The differences:

6 cuts = 3 minutes and 32 seconds
2 scenes with alternative material = Theatrical Version: 6 sec / US/UK Version: 20 sec
Alternative ending = Theatrical Version: 69 sec / US/UK Version: 1 min and 50 sec

On an early morning, little "Tony" has to watch his father "Sam" getting abducted by aliens. A little later, Tony and his mother Rachel have moved and the latter already lives together with a new partner. Tony is still bothered by nightmares about his fathers abduction. He tells his mother that he is still telepathically connected to his dad - Rachel of course does not believe it. One day, a UFO lands somewhere in the middle of the forest and an alien comes out. He gets on his way to complete his mission. While walking, he spots a country home in the woods where a middle-aged woman lives. Immediately, the alien breaks in, raids and impregnates her. One moment later, she gives birth to the "kid": She pushes out Sam who had been abducted years ago. Back on earth, all Sam wants to do is to get back to his family. However, he has changed and no longer is human. Once he got back to his family, strange things start to happen and people die....

The 1983 UK-movie "X-Tro" is a mixture of Horror, Science-Fiction and Drama, accompanied by annoying synthesizer music and partially good effects - at least for the time the movie was made. Today, nobody would really get excited because of the movie. The fact that the movie was included on the "Video Nasties" list probably helped its popularity. Today, the movie had been taken down this list. In 1990 and 1995, two sequels were released that are not really connected to the story of the first movie.

Regarding the versions, it is interesting to notice that there exist two different endings. While the German ending is rather positive, the UK and US version show a different, bloody ending without a happy end which the director thought was appropriate. Still, the original Theatrical Version had the happy ending - the alternative ending was solely included in home theater releases. Several releases include both endings. Apart from the different ending, the US/UK version additionally misses out on a few rather uninteresting sequences which are irrelevant for the story.

We want to thank magiccop who provided us with the DVD for this comparison.

20 min
The camera pans up the dwelling house. After that, the camera fades into Rachel's apartment. Tony is sitting at the table during breakfast and plays around with an action figure. He tells his mother that she should watch what his figure is able to do. Rachel does not really care and tells Tony to finish his breakfast. Then she calls for Analise. When the latter does not react, Rachel tells Joe to get Analise.

Sam, Joe, Rachel and Analise are sitting at the table and talk. Annalise says that Sam looks much younger on the picture. Rachel does not really agree. Joe adds that Sam's journey might have been some sort of rejuvenating cures.
After Joe's remark, Rachel looks at him seriously. Then the camera cuts to Tony in his room. He looks at the gyroscope that is lying on the floor. Subsequently the camera fades back to Sam and the others. Then follows some more dialog.
Analise says that it is weird that they had been a part of Tony's dreams. Sam is happy to hear that and says that Tony probably missed him.
32 sec

40 min
After the scene where the gyroscope spins in circles by itself, only the Theatrical Version includes a shot of Sam and of Analise whilte they talk. The US/UK Version instead shows a shot of Analise, Sam, Rachel, and Joe who sit at the table and which was already shown in the Theatrical Version. The dialog between Sam and Analise is still included an can be heard during this shot of the group at the table. Sam asks, if he is nice to her and Analise responds that they get along well and that he will not let her go. Then she wants to know, how long Sam is going to stay.

Both versions have a different ending. The Theatrical Version ends with a happy ending – the US/UK Version doesn't.

In the Theatrical Version, the shot of Rachel sitting in front of the trees is a little longer. The camera fades out. In the next scene, we see Rachel sitting in front of a closed door – light shines through. She walks to the door and opens it. Then she enters the room and faces several alien clones of her son. The clones touch Rachel and call her "Mama". She smiles down at them. Again, the camera fades out, followed by a title card that says "The End".
In the US/UK Version the camera at first shows the house from outside and then pans upwards. Subsequently, we see Rachel inside the house in front of the closed door with the light shining through. She approaches the door and enters the room. Inside a box she finds a few alien eggs. She picks one of them up to take a look at it. Suddenly, the egg cracks open and a slimy proboscis comes out. It attaches itself to Rachel's mouth and blood splashes out. Rachel falls to the ground and does not move anymore. The camera zooms out and the door closes. After that, the credits roll.
