In 1976 he did a made for Tv film The Time Travelers probably a pilot for never made series. In this film the country is being ravaged by a disease that hadn't been seen since the 1870's . There was a doctor living in Chicago at that time who had found a an effective treatment to this disease that is ravaging the present. Though they know about the Doctor, they don't have any of his research records because he and his records perished in the the great Chicago fire of 1871. There is organization funded by the government that has discovered time travel, what they do is send two doctors back in time to find out from the 19th century Doctor how he cured the disease. One the problems is they have to send him at point just before the fire breaks out. The other problem , they won't be able to do anything to change any history. It wasn't a bad film and it might have made a good series.
