 Several names in the script refer to characters in earlier Westerns.  "Will Munny" is a variation of "Will Penny". Munnys children are  named "Will" and "Penny." Little Bill Daggets last name is borrowed  from _True Grit (1969)_ (qv) as is the name Quincy mentioned in the  dialogue. Instead of an English Bob, there is a Mexican Bob in "True  Grit".
