Invasion is a 1966 low-budget British science fiction film, directed by Alan Bridges and starring Edward Judd and Yoko Tani.

At the hospital, which is surrounded by a mysterious force field, the patient recovers consciousness and explains that he is a Lystrian, and crashed while transporting two prisoners to another planet.

Edward Judd is the scientist battling the extraterrestrial Oriental women in spacesuits, in an efficiently made and, yes, mildly exciting slice of cut-price science fiction.
