There aren't many films which have the same concept as ours. We found a really good example of a similar  film, its called single white female.

  Basically the girl 'Hedy' used to have a twin sister but she died at a young age. 'Hedy' then blames herself for her sisters death and proceeds to find herself another 'twin'. 'Hedy' answers an advert from annie who is looking for a roommate, and slowly becomes annie by copying her hairstyle, clothes and lifestyle. Annie finds out that 'Hedy' is really called Ellen and has killed previous girls who she wanted to be 'twins' with. Annie must escape from 'Hedy'/Ellen before she too is in danger.

   This is similar to our film in the fact that its about twins and jealousy and almost revenge. 
Another film that we have found is called Dead Ringers, this is about twin brothers who ultimately suffer from psychotic tendencies. It is again similar to ours as in the film the two brothers compete against each other and rival each other. This is a good film to compare to ours as the themes in this film are very similar to the themes in our film.
