The opening theme is the coolest ever. It has that jazzy, suspenseful, space-age groove that takes you back to the early 60's era portrayed in the movie.

Once I discovered it was done by John Williams, things started to click. The arrangement and themes actually go back way before he was famous. Back to an era he may not want you to remember. Back when he was known simply as "Johnny" Williams.

First, notice the melody and pace of the creeping marimbas and bubbling flutes. Next, catch a repeat of the old Sci-Fi, TV Fairy-Tale known as "LOST IN SPACE." Listen for the incidental, suspense-scene music throughout. Did you catch the composer's name in the credits?

Bingo!(and still very cool)!
