Legends of the Hidden Temple (also known as Legends of the Hidden Temple: The Musical Movie) is a Mexican-American live-action musical adventure fantasy film inspired by the mid-1990s game show of the same name. This is a sequel to the TV movie, where the three siblings, now with an adopted brother from Mexico, who was an orphan, return to the Hidden Temple Park, realize that the curse in a temple, despite the people were already free in the TV movie, and must decide to rebuild Miztec, by closing down the park for good to make way for the re-foundation of a fictional Mesoamerican civilization called the Miztec Empire, and restore honor of the Hidden Temple by renovating it. The film will premiere in theaters on November 5, 2019. Announcements are made that Isabela Moner, Colin Critchley and Jet Jurgensmeyer are to be replaced due to puberty.
As same as the leaves sequence from that game show called Legends of the Hidden Temple, Olmec (Dee Bradley Baker), instead of announcing the start of the Legends of the Hidden Temple game show and introducing Kirk Fogg, he tells the audience a story of how the curse was made by him to stop Thak from rising into power to cause tyrany in the Miztec Empire as a sacrifice, and told the history of the game show. Also, he learned the viewers a lesson of how the curse was partially broken by the three heroic siblings, Sadie, Dudley and Noah, and told the audience that the curse wasn't fully broken yet.
After the intro sequence and taking place a year before this movie and during the TV movie, the female announcer welcomes the audience to the Hidden Temple theme park, and introduces Kirk Fogg, in style of Olmec, but is accompanied by Olmec's narration about how Kirk Fogg met Sadie, Dudley and Noah. He thank the people, and welcomed the Hidden Temple theme park, and introduces himself. Then as people, feeling bored, are prepared for an adventure of the lifetime, he presents the temple door, and decribes it that the temple was so ancient that inside was those treasures are protected by mysterious temple guards, and only Olmec knows the legend behind those treasures. But before the break, he gives the people a song about the park and Kirk Fogg himself ("Kirk Fogg"). As the song ends, Sadie, Dudley and Noah met him for the first time.
After the song, the scene cuts to present, about a year after the Pendant of Life is recovered back to Olmec, where Sadie, Dudley and Noah are using a raft to cross the moat to an Italian-styled opera-like song they would sing ("Crossing On the Moat"). Kirk Fogg is seen fishing a blue barracuda.
