Space 1999 and 2001 visually look like they are from the same universe.
The 1970's just had a look all its own.
Wasn't 2001 made in the 60's?
Yeah, late 1960s, designed in the latter half. 2001
and Space: 1999
were released less than a decade apart. The look of Space: 1999
was heavily influenced by 2001.
