Caidin's fiction incorporated future technological advances that were projected to occur, and examined the political and social repercussions of these innovations.

Caidin's 1964 novel Marooned, about American astronauts who become stranded in space and NASA's subsequent attempt to rescue them, is based on Project Mercury.

The book was adapted into a 1969 movie of the same name starring Gregory Peck, Richard Crenna, David Janssen, James Franciscus and Gene Hackman, with Caidin making a brief appearance as a reporter describing the arrival of the rescue vehicle at Cape Canaveral.

Caidin's other books with movie tie-ins include The Final Countdown and novels featuring adventurer-archaeologist Indiana Jones.

The one-hour broadcasts were co-written and produced by Bob Judson, and taped at the Nautilus Television Studios outside of Orlando, Florida.

Among those whom Caidin confronted on Face to Face were Rabbi Meir Kahane, head of the Jewish Defense League (who would be assassinated a year later in a New York hotel lobby), Matt Koehl, successor to George Lincoln Rockwell as head of the American Nazi Party, Dick Butler of Aryan Nations, journalist Charlie Reese, and John McMann of the John Birch Society.

Caidin was a friend of 1960s talk show host Joe Pyne, and used the same confrontational interview style, combined with research.

Caidin, known as a stickler for technical detail, incorporated supernatural elements in his Bermuda Triangle novel Three Corners To Nowhere (1975).
