Mention Dick Tracy and a comic strip comes too mind with criminals with strange names. The film opens with a murder of a school teacher that is stabbed and an extortion letter is found on her, signed by splitface. Only $500 is demanded from her while the mayor's price is $10,000. Dick Tracy must find this splitface. Many suspects are found but either they disappear or are killed. Good film to watch if you are interested in a manic that slashes people with a knife.
