this movie be a gem . an undiscovered gerry anderson classic . the origin of both ufo and space 1999 be obvious from this movie and include the cast list which include the late ed bishop and george sewell who both go onto ufo . it be unfortunate that anderson and despite his many tv success and do not get a chance to develop his talent on the big screen . just think what he could have do with the movie version of thunderbird ( which he quite rightly disown himself from . ) . i be sure if you give jttfsots or doppleganger a fair chance you will appreciate it good quality .
