As with Lost in Space, John Williams' original theme to Land of the Giants is perhaps the less well known, even though it's a very catchy horn theme with the off beat backing that Williams favoured for his Allen television themes. However, but more dramatic second season tune is even better and probably the only theme tune in history to benefit from the inclusion of a vicious sounding cat. Williams' score is considerably more interesting than those from Lost in Space, everything is much more bold and dynamic, there is both a keen sense of drama and a much more assertive musicality, the feeling of marking time is largely absent. The result is dramatic and filled with more characteristic Williams flourishes. There is a keen sense of urgency and danger throughout, but also more impressionistic touches to complement the strange new world.
Courage's score is equally dramatic, but not quite the musical equal of the Williams. Courage takes a slightly more stately approach and lives with the limitation of the orchestra's size, whereas Williams seeks to make the ensemble sound more grandiose than it actually is and actually succeeding. A few segments recall the melodrama of his Star Trek scores and are certainly the most notable moments. Both scores are historically interesting and Williams' contribution is perhaps the most enjoyable of his Irwin Allen television scores. However, they still retains that unmistakable feel of TV scoring, particularly in Courage's music which has stretches where sections of the ensemble play occasional notes that are clearly just sign posting the onscreen action. True, this is music not written with the soundtrack listener in mind, but fans of the show or those with a penchant for nostalgia will find more to enjoy here than the casual listener.
This album is also available as part of The Fantasy Worlds of Irwin Allen boxed set and can be purchased here.
