After Flash Gordon showed the studios that comic strips were fertile material for serials, Republic Pictures turned to one of the most popular comic strips--Dick Tracy. Dick Tracy had debuted in the Detroit Mirror in 1931. It soon afterwards appeared in the New York Daily News and the Chicago Tribune.

By 1937, the comic strip boasted circulation in excess of 700 newspapers. With a strong, built-in audience, Dick Tracy was perfect material for a new serial.

Republic grabbed up the rights to the Chester Gould comic strip; however, Gould insisted on a contract requirement that the screenplay be submitted for his approval. Considering the large number of changes the Republic writers wrought on the comic strip, it's a wonder that Gould didn't throw a fit--let alone, approve the script. Republic changed Tracy from a police detective to an FBI agent; Tracy's girlfriend, Tess Trueheart, was eliminated in favor of a simple secretary/lab assistant, Gwen Andrews; and Pat Patton, Tracy's colleague, was replaced by two characters, a bland sidekick, Steve Lockwood, and a goofy, child-man sidekick, Mike McGurk (played by Smiley Burnette). In addition, the writers created a new villain instead of relying upon one of the familiar ones from Tracy's rogues gallery. And to top it off, they gave Tracy a brother.

After Ray Taylor and Alan James directed the first serial, the subsequent entries were turned over to William Witney and John English. As a result, the first serial looks and feels different than the ensuing ones. For starters, Dick Tracy is more serious. Almost all the comedy is relegated to Smiley Burnette. In the subsequent entries, Witney and English would create a lighter mood, more similar to the comic strip. But the first serial is dark. It even pits brother against brother as the Spider, an underworld crime boss, kidnaps Gordon Tracy and operates on his brain--leaving Gordon an evil automaton who behaves the Spider's every word. "By means of this operation--a simple altering of certain glands--he will be unable to distinguish between right and wrong," says Morloch (John Picorri), the Spider's head henchman. Gordon sports a scar on his face, a white streak in his hair (sort of like the Bride of Frankenstein), and a zombie-like stare. Directors Taylor and James even manage some pathos when Tracy discovers that he has been battling his own brother. "Brother against brother--one good, one evil. Ahh, I wonder which will win?" says Morloch.

One of the strongest reasons that the first serial is the best is the villain, the Spider. He's one of the best villains in serial history. Alternately called the Spider and the Lame One, the villain creeps through the shadows, dragging his clubfoot and making the hairs stand on his henchmen's necks whenever they hear him coming. "He isn't human!" a member of his own gang says. The serial contains several eerie sequences as the Spider slowly, methodically stalks his prey down darkened hallways and alleys. But he isn't just a shuffling bogeyman. He also controls a huge flying "Wing" that soars the skies and wreaks havoc on his enemies. (The "Wing" footage would be reused in The Fighting Devil Dogs.) With huge speakers hooked up to its underside, the Wing lets loose a powerful blast of sound waves that can destroy entire buildings. At the end of Chapter One, the Spider uses the sound waves in an attempt to destroy the Bay Bridge in San Francisco.

To keep the mood from getting too dark, however, the screenwriters did hang onto one element from the comic strip, a boy who becomes Tracy's sidekick. The boy (Lee Van Atta) helps Tracy capture the murderer in Chapter One: "It was a pretty good tackle you made there, son," says Tracy. "Aw, gee," says the boy, "that was nothing. You're Dick Tracy, aren't you? I'm just an orphan. Some day I'm gonna be a G-Man, too!" And Tracy says, "Well, now's a good time to start, come on!" And the boy instantly becomes part of Tracy's stable of sidekicks. "I'd like to keep this little rascal with me for awhile."

The screenwriters also do an admirable job of transferring the comic strip's emphasis on the importance of lab work for crime investigations. For example, Tracy and his crew discover that a crime note was written with a typewriter that uses a replaced letter "g." As a result, the FBI agents swarm over the city, looking for the typewriter. At another time, Tracy and his crew, discover the footprint of one of the Spider's henchmen contains sesame seed oil--which means the hideout must be in a vegetable oil importing house. It's fun to watch Tracy's crew working in the laboratory to unravel the clues--this isn't just mindless action. The serial emphasizes the role of brain power in capturing criminals.

The serial also contains some of the comic strip's nifty secret gadgets, such as a knife ring that Tracy uses to cut through some ropes that bind his hands in one of the later chapters.
