The DVD includes four alternate endings. The DVD also has a branching system which includes four different versions of the film.
Fox submitted two versions to the BBFC: The International Version (101m1s) and the Domestic Version (100m47s). Both versions were passed '15'.
Both the international and domestic versions submitted to the BBFC were actually released to UK cinemas. One version ends with the Dakota Fanning character being kept in the hospital, the other sees her staying with the Famke Janssen character, drawing a picture of a two-headed figure.
