[6] Hamblin initially trained at art school for six months but decided on a career in acting instead, and he studied drama to become an actor.
[6] After emigrating to Australia, Hamblin continued to work in theatre over 25 years, from 1970 until 1995, including Blithe Spirit and a stage show of Play School.
[8] In 1967, Hamblin made an appearance in the cult British TV series The Prisoner in the episode "A Change of Mind".
[10] His TV credits also include Number 96, Class of '74,[11] The Young Doctors (as Dr Dan Wheatley),[12] Case for the Defence,[13] and Sons and Daughters.
[4] On the show, Hamblin would sing, read stories, make crafts, play with the toys and educate children about such things as telling the time and the days of the week.
[18][19] Many bloopers of Hamblin's time on Play School have since resurfaced, most of which feature him forgetting lines or making sexually explicit jokes.
