 The DVD release of the complete series (or "Season 1" as the packaging calls  it) features a few changes to the opening title sequence. (1) The image of  Rod Serling (qv) on the gallery wall was replaced with a spiral vortex. (2)  The theme song has been changed from a piece that barely sounds like the  original 1959 series theme to a piece that sounds exactly like the original  theme. Consequently, the credit "Twilight Zone Theme Music Adapted by Don  Harper" in the end credits has been removed on the DVD.
