By 1961, splatter guns, bouncing flappers, and real gangsters of the 1920's were a hit on TV, especially with The Untouchables (1959-1963). So it's not surprising the formula would find its way into the movies. Real life gangster Arnold Rothstein (Janssen) gets the treatment here, except there're no splatter guns or much action, but there is lots and lots of talk. Spread out over nearly 2-hour time frame, that's a tough challenge for any 20's crime film. Then add Janssen's turn that's notably low-key and generally emotionless, and the upshot is a disappointingly listless crime film.I guess the film is best taken as a character study built around a favorite Hollywood theme of one man's rise and fall on the ladder of success. The narrative's mainly about how slickly Rothstein maneuvers through the echelons of urban crime. There's some interest in his conniving, but the account gets draggy with too much slow pacing and mechanical editing. Then too, Dianne Foster's role as AR's ladylove further stretches out the narrative. It's like the producers are also using the movie to promote her career.Anyway, Janssen was soon to star in that classic chase series The Fugitive (1963-67), where his thespic skills could really shine. On the other hand, I'm not sure what the producers were reaching for here, perhaps an abrupt departure from the Cagneys and Robinsons of old. But what they got instead was a sluggish result that now dwells in well-deserved obscurity.

You would think that it might be difficult to make a dull movie about the "roaring" twenties. This movie succeeds in spades. The lead actor (TV"s The Fugitive) is as stiff and flat as any ever seen on the big screen. Most of the performance involves staring down and looking up once in awhile with a half smile.In fact only big little Mickey Rooney shows any life and thus through contrast steals the shallow show where the most exciting scene involves the transportation of a racehorse. Of all the The Untouchables rip-offs of that era this is the worst. There is very little violence, except a punch thrown now and then, and very little else worth watching in this slow as sludge, talky, unconvincing Biography. What we are left with is a TV looking widescreen film that has nothing in its scope. This movie is so bad that maybe we should turn our binoculars around just to get a laugh.

With a screenplay by Jo Swerling, this should have been a dynamite movie. However, with direction by Joseph M. Newman, it winds up being a pointless B movie. No action, no movement, not even really any clear character....Given a desire to portray an enigmatic character, David Janssen was a potentially perfect choice for the role of Arnold Rothstein, boss gambler and the man who may have fixed the 1919 World Series. Janssen had a striking ability to show an intelligent character clearly engaged in the moment even as he evaluates the situation disinterestedly, an acting ability that he used to perfection on the small screen in both THE FUGITIVE and HARRY O. Yet, except for his scenes with Mickey Rooney (who finally got the chance in this movie to stretch himself in a real acting assignment and comes off as the best in the cast), we get little of that. Instead we get a movie in which each plot point is mechanically foreshadowed and then shown in a rather dull fashion.There are a few standout performances: Dan O'Herlihy as the corrupt cop is great, but all he does is make you wish the movie is about him. What's going on in his mind and why? Joseph Schildkraut handles his couple of scenes with dignity and care. Jack Carson slides through his role as the head gangster in his typical bluff, understated manner. But the center of this movie starts nowhere, leads nowhere and takes no advantage of any of the strengths of the talents involved.

I am hardly a fan of national film critics, but they are right on the money with this one - it stinks. One major objection is having David Janssen playing the gangster Arnold Rothstein. What kind of casting is that? He couldn't be less credible in that role. Other cast members don't fit in here, either. The whole thing is a mess. The first half hour of this movie doesn't exactly grab your attention, but when the romance sets in, it really puts you to sleep....and really never recovers. "King of the Roaring Twenties" sounds like an interesting, exciting gangster film but is just the opposite. Don't waste your time.
