And here's what SG #69 from July of 1994 (a year since the first announcement in July of 1993) had to say about DC's proposed movie based on the '91 DS Series:
Zero progress...
I do honestly think that the main reason this never moved forward was because no studio was willing to finance it and DC wasn't willing to finance it on his own. But I also think that Uncle Roger has an excellent point and another major contributing factor could have easily been that the actors had other commitments that they were unwilling to break. At first I was thinking that during the time the film was under consideration only Roy Thinnes and Joanna Going had ongoing commitments because he was playing a major character on
One Life to Live and she not only shot
Wyatt Earp with Kevin Costner, she did a play in NYC, but they were hardly the only ones with other commitments. Now I recall that Ben Cross did a few made-for-TV movies as well as at least one theatrical - Lysette Anthony did a few theatrical movies - Jim Fyfe did several plays, as did Julianna McCarthy - Michael Cavanaugh did several TV guest roles, as did Ely Pouget - Joseph Gordon-Levitt did roles in several theatrical movies - and Adrian Paul, who may or may not have even had a part in the proposed film, was committed to his series
Highlander. And those are just the things I can now think of off of the top of my head. Scheduling a time when the cast would have all been free to do the film would have been a nightmare. And if the studios were aware of that, that could easily explain a good part of their reluctance to take on the project.
