Peter Thomas "did" the soundtrack for "Chariots of the Gods" too. Beautiful soaring music.
Perry Rhodan books are quite the phenomenon. Started by a team of writers in the 60s and still being regularly published today !!!!!.
I think they're over 3000 books to date and still going. I "discovered" them in the late 70s and read some out of sequence, and am currently ploughing through the online English translations - up to 92 and still going and loving them.
They're big in Europe ( non Brexit
) but massive in Germany, with a lot of diehard fans in a few other countries.
The movie "Mission Stardust" 1967 ? was panned by critics but it wasn't bad for the time and Thora was very nicely cast
.
Nice music too, Italian composers always do very well.
