Dear folks, by the standard definitions of "canon," the ONLY canon for the Original DS universe are the actual aired episodes of the original series. Stuff that was in the "Marilyn" Ross novels, the Gold Key comics, the feature films, or even Sam Hall's (in)famous TV guide article isn't canon. It either refers to its own iteration of the DS universe (yet another layer of "parallel time, " perhaps?) or represents commentary from "interested parties." Sadly, even the wonderful video of a fabulously coiffed and gowned Joan Bennett filmed by a fan in the 1980s telling us that Elizabeth was indeed Vicki's mother does not count as canon. (From the clues dropped in the 1966 scripts, a very different solution to Vicki's parentage is implied, though had Art Wallace continued to write for the show, who knows what final twist he might have introduced had the matter been resolved in an aired episode.)
The Depp movie, and its potential sequels, will establish the characters and story in their own unique universe. The storyline and revelations of that world already present a very different history for the Collins family from the narrative, fraught as it was, established for the Collinses we knew in the Sixties.
