An interesting bit of tidbit about the actual novel, an important character not in the movie is a Russian "cleaner/assassin" named "Leon", which reminds me of of "Victor", the cleaner in La Femme Nikita, whose character was the basis for Leon, the Professional, both by Luc Besson. See https://books.google.com/books?id=vorkBgAAQBAJ&q=leon#v=snippet&q=leon&f=false . If somebody can please verify this who has also read the book. — Preceding unsigned comment added by 47.136.219.44 ( talk) 23:29, 4 August 2018 (UTC) reply
