Ryan Reynolds is today best known as the merc with the mouth for his role as Deadpool. He was in a string of both romantic comedies and comedy movies such as The Proposal, Just Friends, The Hitman’s Bodyguard and Definitely, Maybe.
When he was younger, he had guest starring roles in shows like The X-Files (where he was murdered in the opening scene) and many have thought that they recalled him as one of the children on Little House on the Prairie.
Ryan was born two years after she show premiered, so he was too young to appear for the majority of the seasons of the show. And his first television or movie credit wasn’t until much later, in 1991 when he starred in the television series Fifteen. So he was never a guest star on the show.
