One might think that Warner Brothers, the Hollywood studio that gave us so many fine films in the tough guy-mean streets-cops and robbers genre, who arguably created the world's image of the American gangster, could put out a TV series about such men and those themes. Alas, there are no Public Enemy or Little Caesers here. The studio instead relied on their TV production formula; load the cast with handsome hunky guys, and alternately star a different one each week. This worked well with 77 Sunset Strip and Maverick, where most of these fellows had a personality that could get them through, and beyond the series. Not so much here, with bland character actors like Mike Road and Donald May doing the work. Instead of the fast-paced, wisecracking urban lowbrows that inhabit Warner Brothers flicks in the 1930's and 40's, They seem to be square college boys turned reporters that fall into crime stories. The stories themselves have little to do with the Untouchables, or the cynical milieu of the great Warner pictures of the era. They are highly melodramatic, insincere tear jerkers or just stupid, like an episode where Voodoo dolls came into play.
The look of the series is cheap too, with a shameless overuse of vintage stock footage and bits of older films, including the actual film, The Roaring Twenties (1939). Often not even the slightest effort is taken to clothe or hairdress the performers in period style, the girls sometimes look like they just walked off a 1961 Dior runway. Even the stock footage will show 1950's cars in use.
The producers probably looked upon their show as nothing more than a fake Untouchables, so they put in something that Ness and the boys never much bother with- music! Every episode has at least one number, sung by Dorothy Provine in her antiseptic "Speakeasy" set. Though Warner Brothers had a large library of music , and even pioneered the film musical, most of the songs used are pop tunes predating that. She delivers her 50's Vegas lounge act versions of old croakers like Has Anybody Seen My gal?. If memory serves, they emphisized this as a draw for the series, and had even issued an album by Miss Provine commemorating it. Ironically, the theme song is one of the worst ever written-with lyrics like "The roaring, never boring, twenties" and rhyming "gun molls" with "fun molls".
