Actor Austin St. John has admitted in interviews that, while he enjoyed working on "Mighty Morphin Power Rangers", he had mixed feelings about the fame that the show had given him. Mr. St. John admitted that, because he was recognized as the Red Ranger by fans, he had to move into different homes twice due to fans that would follow him to his home, he had to get sensor lights on his home, and he once literally had the clothes ripped off his back by Power Ranger fans when he tried to enter a local mall to go shopping. As a result, Mr. St. John has said that he will take photographs with his fans, sign autographs and talk with them, but he remains very protective of his private life.
In Malaysia, as part of its campaign against drugs, the word "Morphin" is censored, by substituting or muting footage where the word is spoken (the phrase "It's morphin' time") or displayed onscreen, for fear that it could encourage children to become addicted with the uses of morphine. When it was broadcast on RTM (along with its toy commercials), it was called Mighty Power Rangers, or simply Power Rangers or Power Ranger.
