Rome is falling, crumbling into disrepair. In the last five years there have been five Caesars, and every one was murdered. Now the title of Caesar, highest office in Rome, must fall to the shoulders of a young boy, Romulus. Scared, naive, and unprepared, he is barely on the throne for hours when the dreaded [[AlwaysChaoticEvil Goths]] descend upon Rome. Deposed and exiled, Romulus is rescued by a small band of loyal warriors, but not before uncovering an ancient prophecy. Pursued by the Goths, the heroes are led by the prophecy to faraway lands where Romulus must find his destiny.

An action adventure movie made in 2007, staring ColinFirth, BenKingsley, AishwaryaRai and [[Recap/DoctorWhoNSS3E9TheFamilyofBlood that psychic kid from]] ''Series/DoctorWho'', loosely based off a novel of the same name by Valerio Massimo Manfredi.

----
!!This film contains examples of:
* ActionGirl: Mira. Dear gods, Mira. She plows through an entire army of Goths holding Romulus prisoner. Apparently she became her culture's equivalent of a black belt at age ''fourteen''.
* AncientRome: Technically still counts, though it covers (in a fictional sense) the final events of its history.
* ArchEnemy: Wulfila to Aurelius. [[spoiler:Vortigern to Ambrosinus.]]
* AnAxeToGrind: Wulfila.
* ArtisticLicenseHistory: It's VeryLooselyBasedOnATrueStory since the the last Emperor of the Western Roman Empire was indeed a boy who did disappear from history. [[spoiler:But then it ends up being a prequel to the [[KingArthur Arthurian legend.]]]]
* {{Badass}}: Aurelius. Though he also has shades of ActionSurvivor.
* BigDamnHeroes: [[spoiler: The eponymous Last Legion.]]
* BigBad: Appears to be Odoacer the Goth, but [[KarmaHoudini he disappears from the plot]] after the heroes give up Rome as lost, and his erstwhile [[TheDragon second-in-command]] Wulflia emerges as the true main villain of the movie.
* TheBigGuy: Batiatus [[ScaryBlackMan might look it]] and he uses a big sword, but he's really a GentleGiant and the best fighter among the heroes is Mira.
* BloodlessCarnage: The movie seems to go out of its way to avoid showing blood being spilled, including some rather ugly JumpCuts to other characters reacting to a death when a blow is hit, ''then'' back to the original (now dead) character.
* TheCaptain: Aurelius.
* CoolSword: The sword of JuliusCaesar. Serves as the MacGuffin. [[spoiler: Eventually became Excalibur.]]
* DualWielding: Demetrius uses a pair of swords.
* GoingNative: Upon finding a prophecy that leads them to [[spoiler:Britain]], the heroes look for the Ninth Legion, presumably the "last legion" loyal to Rome. But they've settled down as farmers. [[spoiler:What Romulus does in the end. He becomes King Arthur's father.]]
* FaceHeelTurn: After Rome falls to the Goths, the Senate and an official of the Eastern Roman Empire secretly send people to rescue Romulus and take him to Constantinople. But later they betray the heroes anyway after recognizing Odoacer as legitimate.
* HistoricalHeroUpgrade: Happens to both Aurelius and the young Emperor Romulus.
* HistoricalVillainUpgrade: Odoacer, king of the Goths
* IronicName: Romulus the last Roman emperor was named after the founder of Rome. TruthInTelevision.
* LadyOfWar: Mira.
* LastOfHisKind: Aurelius and three men are all that remain of their Legion.
* LostRomanLegion: [[spoiler:The Ninth Legion appears in the movie, as the titular legion]]
* LuckilyMyShieldWillProtectMe: Vatrenus uses a sword and buckler.
* MaybeMagicMaybeMundane: Seems to be superstition, legends, and old cults, and maybe just a little bit of good luck, Romulus's mentor Ambrosinus is revealed to be [[spoiler: {{Merlin}} in the last few minutes of the movie. Then again, his only magical act seems to be that he hasn't aged.]]
* TheObiWan: Ambrosinus, looking like an {{Expy}} of Gandalf the White.
* OnlyKnownByTheirNickname: Aurelius goes by that name for most of the movie, until in one instance he reveals his full name is "Aurelianus Caius Antonius". Huh.
* PlayingAgainstType: ColinFirth, best known for his romantic comedy and drama roles, as a ancient Roman swashbuckler.
* PraetorianGuard: Aurelius is the general of the Emperor's bodyguard, comprising a legion. They're not actual Praetorians, though - those were disbanded centuries earlier.
* RaceLift: The Indian warrior Mira was an Italian named Livia Prisca in the original book. It seems like an excuse to cast AishwaryaRai as an ActionGirl in a historical epic... not that anyone is complaining.
* SwordAndSandal: Technically counts, albiet it takes place at pretty much the tail end of the timespan that "Sword and Sandal" covers.
* TrailersAlwaysSpoil: The [[spoiler:KingArthur connection]] is revealed ''immediately''.
* YouKilledMyFather: Wulfila killed Romulus's parents.
