 The movie has two endings; one for the theatrical release, and an alternate  version included in the movies DVD. In the first, after a brief dialogue  with Telly, the man creates an illusion of Sam which Telly chases through the  hangar, and then confronts her again. He reveals that the purpose of the  experiment is not to investigate the children, but rather the bond that  exists between a parent and child, and that he believes it can be broken. He  admits, however, that the experiment has so far produced no positive results  with regards to Telly, and that it will fail soon if she doesnt forget, and  he will be responsible for that failure. However, despite him revealing  himself as an alien and almost succeeding by stealing the memory of Sams  birth, Telly can still remember her son, and he is whisked away by an unseen  force, presumably to face the consequences of failure. Reality is restored to  normal, and Telly is the only one who can remember the events that  transpired. The alternate version is very similar, except that Telly is faced  with a facsimile of Sams room. She tries to force her way in, but cannot  reach Sam. The alien scientist tries to convince her to forget Sam, but  fails. He then accepts that the experiment has failed, and explains that she  will be the only one who remembers what transpired there. Reality is again  restored to normal.
