'The Alamo' trailer is being featured in front of 'Kill Bill.' The music being used for it is from the first Gladiator soundtrack released. It's a combination of the first 3 tracks on there - track 1 - 'Progeny,' track 2 - 'The Wheat,' & track 3 - 'The Battle.' I think it's mostly 'The Battle' being used.
I hope this helps any future seekers.
