Stardust

Here's my rephrased version:

In the quaint English village of Wall, nestled beside the mystical realm of Stormhold, lies a stone wall that serves as an impassable barrier between the two worlds. The watchful guardian tasked with maintaining this boundary is no match for the cunning Dunstan Thorne (no actor name provided), who manages to outwit him and cross over into the market-filled streets of Stormhold. It is here that he encounters Una, a captivating enslaved princess who offers him a delicate glass snowdrop in exchange for a tender kiss. As the night wears on, they succumb to their desires, and nine months later, the guardian presents Dunstan with an unexpected gift: a baby boy named Tristan.

Eighteen years pass, and the kingdom of Stormhold is thrown into chaos when the dying King throws a radiant ruby into the sky, proclaiming that his successor will be the first among his sons to retrieve it. The gem hurtles towards a star, and both plummet from the heavens, landing in Stormhold. Two princes, Primus and Septimus (no actor names provided), embark on separate quests to claim the precious stone.

Meanwhile, in Wall, Tristan and Victoria have grown up under the watchful eye of the stone wall. When they gaze upon the falling star, Tristan vows to retrieve it, offering his hand in marriage as a reward for her cooperation. Despite his mother's origins beyond the wall, he is unable to persuade the guardian to grant him passage. It is then that he discovers a Babylon candle left behind by Victoria, an artifact capable of transporting its user to any desired location. Tristan lights the candle and finds himself transported to the fallen star, now personified as the enigmatic Yvaine.

As fate would have it, three ancient witch sisters, determined to regain their youth and powers, set their sights on consuming the heart of the fallen star. Their leader, Lamia (no actor name provided), devours the remnants of a previous star's heart and sets off in search of Yvaine. She conjures up a wayside inn as a trap, intent on capturing her prey.

Yvaine grows weary, and Tristan, left alone to bring her food, promises to return soon. However, his absence is exploited by an unsuspecting unicorn, which releases Yvaine and unwittingly leads her to Lamia's inn. Upon discovering Yvaine's disappearance, Tristan rushes to the scene, only to find that she has been taken captive. The stars whisper warnings of impending danger, urging him to board a passing coach – one that just so happens to belong to Primus (no actor name provided). As fate would have it, they stop at Lamia's inn, interrupting her nefarious plans and allowing Tristan and Yvaine to make their escape using the Babylon candle. They find themselves swept up in the clouds, where they are eventually captured by pirates on a flying ship. The captain, none other than Captain Shakespeare (no actor name provided), claims Tristan as his nephew and Yvaine as a close friend, gifting them new attire and teaching Tristan the art of fencing and Yvaine the waltz.

As Septimus, the sole surviving scion of the royal line, zeroes in on the coveted stone, he discovers that Yvaine's essence holds the key to eternal life. Meanwhile, Tristan and Yvaine surrender to their passion for one another at an intimate inn, their love as radiant as the celestial bodies they've left behind. The next morning, Tristan departs, leaving behind a strand of Yvaine's hair as proof of his devotion to Victoria, only to realize that the lock has transformed into Stardust, signaling Yvaine's mortal fate if she crosses the mystical boundary.

Crushed and bereft, Yvaine stumbles through the desolate landscape, unaware that Tristan has returned to rescue her from the brink of extinction. Una, the perceptive and compassionate witch, intercepts Yvaine's doomed trajectory and commandeers Ditchwater Sal's caravan to intervene. Lamia, however, seizes the opportunity to strike, killing Sal and capturing both Una and Yvaine. The cunning sorceress then transports them to her foreboding manor, where Septimus and Tristan converge in a desperate bid to save their loved ones.

As the unlikely allies burst into the stronghold, Septimus is stunned to discover that Una, his long-lost sister, has been hiding in plain sight. This revelation sets the stage for a heart-wrenching reunion as Una reveals to Tristan that he is, in fact, her son. United by their shared bloodline and determination, Septimus and Tristan eliminate two of Lamia's cohorts before the vengeful sorceress exacts her revenge on Septimus.

With Septimus fallen, Lamia sets her sights on Tristan but is momentarily felled by a poignant flashback to her lost sisters. This brief respite allows Yvaine to break free from her captor and reunite with Tristan, their love now imbued with the celestial magic that has revived her essence. As Lamia makes one final attempt to destroy them, her own dark energies ultimately prove her downfall.

With Lamia vanquished, Tristan retrieves the precious gem, and Una's revelation of his true heritage sets him on a path to claim the throne. As he ascends to royal status alongside Yvaine by his side, the once-star-crossed lovers now reign supreme as king and queen. Eighty years later, they opt for a more celestial form of immortality, using a Babylon candle to ascend into the heavens, where they sparkle together as stars, their love an eternal beacon in the firmament.
