What are the advantages and disadvantages of writing pulps and noir in their original time periods?
On the other hand, writers who are stuck (whether at their own behest or at the dictate of their publishers) to a certain time period can run the risk of just telling the same old plots over and over again. And that gets old fast -- even for pulp readers.
How do you overcome that? Right off the bat, I'd say research. Find something interesting like the Nazi search for biblical artifacts (Raiders of the Lost Ark) or the World's Fair (The Ruby Files) that will breathe new life into your same old setting.
