Sequel ....
Let me give you my take ....
West and Gordon go to London and Dave Jack the Ripper in their later years
I kind of think that it was a missed opportunity by not doing a film about Dr. Loveless' henchwomen. With some alternations, and you could've had an old west/steampunk version of Charlie's Angels.
