Ian...too funny...just a couple of nights ago, "The Time Machine" was on. I couldn't watch it, but I thought about time travel & DS...so, loosely, DS already been there/done that.
Kolchak....terrific..BUT...nowadays I read so many women authors, it would be nice to have some stronger women kicking but (think FAITH!!lol).
Back to the Future was done too (1795 & 1897, Barn/Vicki went back).
Let's see, "Rebecca", "Turn of the Screw", "Dr. Jekyl/Hyde"...the classics.
Now space travel, which since DS has become a commonality, that would be fun to 'explore' (think Julia on Mars!!)
