This week’s puzzle consists of a list of movie titles with something in common. These titles, however, have undergone “Key Word Encoding”. Here’s how Key Word Encoding works:
A key word with no repeating letters is selected. Any time a letter from the key word appears in the text to be encoded, that letter is replaced with the next letter from the key word. The final letter of the key word is replaced with the first letter.
Example:
Key word: THREAD
Key code: T=H, H=R, R=E, E=A, A=D, and D=T
Title to be encoded: THE STRAIGHT DOPE MESSAGE BOARD
Encoded title: HRA SHEDIGRH TOPA MASSDGA BODET
Second title to be encoded: GENERAL QUESTIONS
Second encoded title: GANAEDL QUASHIONS
Note that only the letters that appear in the key word change. All other letters remain the same.
The 7-letter key word in this week’s puzzle describes the common factor in the 16 movie titles. Another meaning of the key word relates to a certain aspect of moviemaking. All movie titles below are encoded using this same key word.
To complicate matters, the encoded movie titles have been broken into pieces of two, three, and/or four letters and then alphabetized according to piece length. Can you determine the original movie titles and the key word?
