Probe, later to become the TV series "SEARCH" (72-73 on NBC) was an attempt to cash in on the publics fascination with high tech from the space program. The movie had all the pieces of a fun romp: sci-fi with the hight tech scanners and communications, intrigue with the search for the NAZI theft of the French "Entourage" diamond collection, and locations spanning from Innsbrook Austria, the Gulf coast, and New York City, though I think all of the filming was done in southern CA with the Angeles National Forest doubling as the Austrian mountains and forests. The movie was well written, acted (it was great having older, more cerebral actors on the show) and produced, and the show started out that way until I think they ran out of ideas. Having three different agents (Hugh O'Brien, Tony Franciosa, and Doug McClure) was a mistake I think as it did not allow a fan following to develop for one main character. It would be great to do the series today, but I think there would be too much of a temptation to put young pretty boys instead of older more competant (and believable) actors in the agent roles.
