One thing that many people remember about TVB's 1981 adaptation of Jin Yong's DEMIGODS & SEMIDEVILS is its inaccurate ending, with Mo Yung Bok killing the Janitor Monk, learning godly martial arts, and becoming a menace that even Kiu Fung, Hui Juk, and Deun Yu couldn't defeat.
The thing about DGSD '81, however, is it only started getting off course towards the end of the story (basically, from the point that Mo Yung F'uk murdered Deun Jing Tsun's lovers). Most of DGSD '81 was more-or-less accurate to the novel (as far as I know) until about three-quarters of the way into the story, and then the series went from minor deviations to wholesale rewrite of the ending.
I have a theory: I believe that TVB originally planned to make DGSD '81 a more-or-less accurate adaptation all the way through, but for reasons unexplained changed its mind halfway into production.
The main premise for this theory lies in scenes shown only in the opening titles for Part 1 of DGSD '81 (e.g. 6 MAK DIVINE SWORDS SAGA). In those opening titles, we see such scenes as Yau Tan Tze and Ah Chi in the company of Beggar's Union Elder/Chief Cheun Gwoon Ching, and a crazed Mo Yung F'uk struggling maniacally against invisible enemies before being comforted by Ah Bik. Such scenes are accurate to the DGSD novel, but were *never* shown in the completed episodes of DGSD '81. In the episodes, Yau Tan Tze never became the temporary Beggar's Union Chief (he had no affiliation with the Beggar's Union at all in the series), and Mo Yung F'uk never went insane in DGSD '81, but ended up accidentally killing himself while trying to murder Deun Yu.
Judging from the difference between the opening titles and the completed episodes, it looks like TVB originally *did* plan to adapt DGSD much more accurately in 1981, but for some strange reason, changed its mind and went for that infamously altered ending instead.
What do you think?
