Jon Provost was one of the child stars of the 1950s who is best remembered for his role in Lassie. According to the actor, he was already immersed in the entertainment industry even before he became three years old. At the age of four, he was already part of The Country Girl where he worked alongside Grace Kelly as well as Bing Crosby. It was in Lassie that the young actor truly shone.

As a matter of fact, Lassie and Provost became a power duo that they were always together when doing guest appearances! Provost gave all the credit to the three Lassies that he worked with during that time as they helped him become a better actor. He took a break from acting to continue his studies. Even after he went on to get a degree at the Sonoma State University, people still remember him for his role in the iconic TV series. Though he is no longer acting, Provost found a lucrative job in selling real estate.
