Career: After his business failed, Van Dyke was a radio announcer for a local station and performed comedy routines. His popularity led to him being signed by CBS. After making his TV acting debut in The Phil Silvers Show, he hosted several long-forgotten game shows before hitting the big time with Broadway hits The Girls Against the Boys and Bye Bye Birdie. That led to The Dick Van Dyke Show, which was a smash hit and ran for five years. Among his other famous projects are Mary Poppins, Chitty Chitty Bang Bang, Van Dyke and Company, and Diagnosis Murder. He continues to act.

Career: Duffy's big break came in 1976 when he landed the title role in adventure series Man from Atlantis. It was axed in 1978, the same year he began playing Bobby Ewing in Dallas. The glossy soap became a worldwide hit and made him a household name. Nevertheless, he quit in 1985, only to return a year later in the notorious 'shower scene', which revealed that the entire previous season had been Bobby's wife Pam's bad dream. Dallas ended in 1991, although he's appeared in several spin-off TV movies and the current revamp. Duffy's other projects include sitcom Step by Step, soap The Bold and the Beautiful, and game show Bingo America. He reprised his role as Bobby Ewing in the revived version of Dallas between 2012 and 2014. More recently, he has starred in the Swedish sitcom Welcome to Sweden.
