Here is yet another twist.

I personally prefer to experience the Hitchhiker's saga via the text version of the radio series scripts (with footnotes). I enjoy the story and humor in this fashion much more then if I listen to the BBC radio series itself. But I must admit, that I would not enjoy the scripts as much if I had not become familiar with the voices of the actors beforehand.

The T.V. series 2nd, The LP records 3rd (far too abridged for my taste)

The first 3 novels I only skim over now and again. But, I do quite enjoy the abridged audio book of Life, The Universe, and Everything read by Stephen Moore (The voice of Marvin in the Radio and T.V. show, and also the LP record version).

Have not seen the film, and have no wish to.
