Released in time to capitalize on the minor success of television's The Time Tunnel, this slapdash entry from genre specialist David L. Hewitt (The Mighty Gorga, Gallery of Horror) is heavy on stock footage and light on plot. Wealthy industrialist Stanton (Scott Brady) reluctantly finances a team of scientists including Abraham Sofaer, Anthony Eisley, and Gigi Perreau, who are doing expensive experimentation with time travel. Needless to say, the entire group ends up lost in both the future world of 6968 (where they encounter evil aliens led by Poupee Gamin) and the past of a million years ago (where they encounter stock dinosaur footage from One Million B.C.) when their time machine's ruby-driven power supply malfunctions. Lyle Waggoner is among the familiar faces, most of whom were better utilized elsewhere. Hewitt had dealt with an almost identical story line when he handled the special effects for Ib Melchior's The Time Travelers (1964), and cribbed scenes from the director's The Angry Red Planet for this film.
