Flying saucers from Earth

In several sci-fi movies and TV shows such as "Forbidden Planet",
"Lost in Space" , and "The Twilight Zone", vehicles manned by Earth
people travelling in deep space are of "classic" flying saucer design.
Is such a design feasble in the real world for space travel? Any
particular advantages to it? I think in some flicks flying saucers,
either of terrestrial or extra terrestrial originion rotate at least
the rim constantly while in flight.
