We know Captain Jack got thrown back in time to the 1860s. I want to write a story spanning that period, each chapter a crossover with something appropriate to the period.
1870-80s - a western of some sort - one of the Clint Eastwood films, I think.
1890s - the Buffyverse, Spike's encounter with Dracula and the reason Dracula owes him money. I think that this will be a poker game, or some other card game. Or possibly rat-baiting or similar.
1920s-30s - not sure yet, maybe something set in America e.g. The Grapes of Warth / The Great Gatsby / Thoroughly Modern Millie, but Cabaret might be fun if I can find a plot handle. Or Indiana Jones for that matter.
1966 - Lois & Clark (or Superman Returns for those who prefer that) - Kansas in the 1960s and the arrival of a small capsule from the planet Krypton. I've already written that, but I don't want it to be the first part of the story.
1970s-80s - one of the classic cop shows. The Sweeny? Kojak? Miami Vice? or take it a little later and make it Columbo or Hill Street Blues?
So, suggestions for all of the above (apart from 1966) would be appreciated.
