I think all the mediums are equally valid if the material is good. I’ve worked a great deal in radio over the years; in fact I started out originally working in radio in Ireland before television came to Ireland. It’s a wonderful medium because you get the chance to use your imagination, you can do anything.

An actor can play a character that’s two inches tall or he can play Ben Hur because it’s all in your vocal dexterity and in the imagination of the audience, so I think it’s a terrific medium for science fiction.

I used to listen to Journey Into Space years ago, which I thought was wonderful and I painted all the pictures myself. I had my own image and when they started to draw those characters it was totally at variance to what I had in my head.
