I was just thinking the other day... they should make some cool surreal movie with Mark Twain and Edgar Allan Poe... like a Bubba Ho-Tep meets Naked Lunch or something... Ed would be older than Twain... birth years, 1809 to 1835.
Ed died in '49, so Mark would only be 14... Ed was 40. Maybe Samuel (Mark Twain) Clemmons meeting Ed right before he died...
