Not a trick question
The name is Alex North. The 2 movies he wrote scores for that were not used were 2001 - a non original score was used instead and The 4 Horseman of The Apocalypse . 4 Horseman's director instead had Andre Previn write a new score. 2001 is a classic whereas 4 Horsemen tanked at the box office. Both movies were released by MGM.
Lastly the clue was Spartacus which he wrote the score for and the classic line was "I Am Spartacus"
The 2001 score he wrote which was never used is on CD @ Amazon.
