Back in 1999, around the time that the original DVD boxset was coming out, Austin St. John and Walter Jones hosted a special airing of a Power Rangers episode they called "The Lost Episode". In fact, it was just the unaired pilot of the original series, an episode called "The Day Of The Dumpster". Most of the cast members were the same, except for one key difference: the Yellow Ranger.
Ask any fan who the Yellow Ranger, aka Trini Kwan, was played by and they'll tell you it was Thuy Trang, the then 19-year-old Vietnamese-American actress. But in the unaired pilot, Trini Kwan was actually played by Audri DuBois, a Hispanic-American actress who was later fired for asking for more money. What would have happened if Audri had stayed on? How would Thuy Trang's life been different?
