He is best known for the book series Grizzly Tales for Gruesome Kids and The War Diaries of Alistair Fury; both were adapted into children's television programmes.

Rix studied Drama and English at the University of Kent, and worked as an assistant stage manager at Royal Court Theatre to learn how to direct plays.

[2] On holiday in France, he created a white lie story, The Spaghetti Man, in order to make his four-year-old son eat his dinner.

Rix took note of how the lie had made his four-year-old eat all of his meals without hesitations, which would inspire a series that could scare children into behaving themselves.

[2] The Spaghetti Man would be included in Rix debut book Grizzly Tales for Gruesome Kids,[3] which was published in 1990 by André Deutsch.
