Mason Vale Cotton
Mason could enter the industry after he got the opportunity to portray the character of Bobby Draper on the TV series Mad Men. Vale Cotton earned most of his fame after he started playing the role of Maynard “M.J” Delfino on the TV series Desperate Housewives. He was also the voice of the character Arnold on the animated series Hey Arnold: The Jungle Movie. He should really be praised for what he has achieved at the age of 15.
