Jared Padalecki and Jensen Ackles are American actors who became famous for their roles in the television series Supernatural.
Initially, Jensen Ackles (Dean) was approved for the role of Sam Winchester, but when Jared Padalecki (Sam) auditioned, they decided to change plans and use Ackles' charm in the role of Dean Winchester.
The creators of the series called Jensen Ackles and asked if he wanted to be Dean Winchester. He agreed, and Jared Padalecki got the role of Sam.
When the series first started, Dean Winchester's phone number was the real thing. Then this number really belonged to Jansen (Dean), and when calling this number, you could hear his voice on the answering machine: "This is Dean Winchester. If this is an emergency, leave a message. If you are calling about November 2, 1983, let me know your coordinates."
