Tristan in the movie has one week to bring back the star, while it felt like Tristran in the book took quite some time wandering through the land beyond the Wall. Their time on the airship was also lengthened to give the movie a bit more suspense. The airship captain, known as Johannes Alberic in the book, was flamboya-tized to make the excellent character of Captain Shakespeare, played by Robert De Niro. Quite a few of the book characters are sacrificed to make for a quicker plot, including Tristran's traveling companion the little strange man.

Tristran in the book has a stepmother and sister, and his name is Tristran, not Tristan.

Little does he know, others are pursuing the very same star he is searching for, for a variety of reasons. Tristran/Tristan sets out to find a fallen star to give to his lady love, Victoria.
