When I saw 'The Forgotten' starring Julianne Moore at the cinema, at the end the alien fails in his experiment and gets zoomed back up to the skies. Just seen it on television, and the end is totally different. The alien calls time on his experiment and returns Moore's son. Were two version of the film made, why, and which versions were cinematically released to which countries?

The DVD of The Forgotten offers the possibility to view the Theatrical Release or the Extended Version which contains an alternate ending.

The Extended Version runs 8 minutes longer than the Theatrical version. Basically, the changes consist of 2 scenes that were cut off the Theatrical Release + the alternate ending. If you have not seen this movie yet, GIVE YOURSELF A FAVOR and watch the EXTENDED VERSION. The alternate ending is TOTALLY DIFFERENT and a lot more in tune with the rest of the movie.
