Before they became Hollywood stars, plenty of familiar faces turned up in television shows that most people barely remember. Some played teenagers in short-lived sitcoms, others appeared in crime reenactments, and a few got their start on children’s television. Looking back at those performances can be a strange experience, especially when the actor now seems inseparable from a much more famous character. The hairstyles are different, the clothes have aged considerably, and occasionally the entire show feels like something from another lifetime. A few of these early performances are surprisingly easy to find, too.
