As 95% of The Untouchables episodes were pure fiction one normally did not have to worry about continuity. The episodes were never chronological, this episode is fixed by narrator Walter Winchell with happening in 1934.
Bruce Gordon as Frank Nitti is now working a new racket. Simple extortion of theater owners with smooth talking Richard Anderson fronting the operation along with alcoholic shyster attorney Myron McCormick and the muscle being Gordon and Frank DeKova.
Harry Harvey, Sr. is blinded and another theater owner Dick Foran is killed with a car bomb. Even an Untouchable, Anthony George is killed as well as Gordon who has really gone out of control puts a hit on Robert Stack and his men. As you gather this was one of the bloodiest of Untouchable episodes. And there's more than that.
Bruce Gordon was always a treat with that perpetual sneer and rasp in his voice, he really played Nitti to the hilt. As he always did he adds something to this episode even if the facts just ain't there.
