Neill Blomkamp insists the new 'Alien' movie won't interfere with the 'Prometheus' franchise.

The 35-year-old director has been chosen to helm the much-anticipated new movie and has revealed he amended one aspect of his film to ensure it would not tread on the toes of 'Prometheus 2'.

He said: ''I changed the one thing [Ridley Scott] felt was bumping Prometheus a little bit''

What's more, the director confirmed he already has a title in mind for the new 'Alien' movie, but refused to reveal what it is because it might expose too many plot secrets.

He explained to Empire magazine: ''It's kinda quite bold, but it gives away too much if I say the title.''

However, it remains unclear where the new film will sit in the context of the franchise.

Blomkamp said: ''Where it went after Aliens to me, as a fan, was wrong.''

In an interview last month, the director said he wanted the film to feel like the ''genetic sibling of Aliens''.

At the time, Blomkamp said his film will disregard 'Alien 3' and 'Alien: Resurrection' and will instead carry on from the James Cameron-directed 'Aliens' in 1986.

Blomkamp explained: ''I want this film to feel like it's literally the genetic sibling of Aliens. So it's Alien, Aliens, and then this movie.''
