Sherlock Holmes vs Jason Bourne
Sherlock Holmes, from the Guy Ritchie films
VS
Jason Bourne, from the Bourne films
They are fighting in a small street in 1950s Paris, on which there is a butchers, a bakers, a post office and several other shops, which they can use the contents of, obviously. There are no guns anywhere near them. They start ten feet from each other in the middle of the street, unarmed. To win, one must kill or incapacitate the other. Neither knows anything about the other prior to the fight. They must try not to harm civilians or cause collateral damage.
