 Director James Cameron (I) (qv) fought over the ending with  Executive Producer Mario Kassar (qv). Cameron wanted to end the  film with the alternate Coda Ending (the older Sarah in future) as a  bookend but Kassar wanted to end the film in an another way (as a  measure for possible sequels). He eventually relented when test  audiences and Kassar himself reacted negatively over the coda ending  and changed with the existing one.
