John Daggett is a supporting character in Christopher Nolan's third Batman film The Dark Knight Rises. He is the CEO of Daggett Industries, a major construction company in Gotham City, and a business rival of Bruce Wayne. In the film, he supports the terrorist Bane in order to take over Wayne Enterprises. He is portrayed by Ben Mendelsohn.
Daggett employed Bane and his army of mercenaries to secure diamond mining rights in West Africa before bringing Bane to Gotham City. Daggett worked with Bane and helped him acquire Bruce Wayne's fingerprints with help from master thief Selina Kyle. Selina wanted a clean slate tool from Daggett to erase her past, but he told her when she confronted him that it was a myth.
Daggett had funded the construction of Bane's underground base, his construction workers also helped place bombs over the city and helped Bane and his henchmen with tasks. One of them was stalling John Blake at the stock exchange to help give way for Bane and his men to escape.
For Daggett's attempted takeover of Wayne Enterprises to work, the plan was for Bane to use Bruce's fingerprints so he would break into the Gotham Stock Exchange and put down a list of risky investments under Wayne's name and bankrupt him, lowering the company's share value. Bruce Wayne was aware of this through Lucius Fox, who knew that Daggett bankrupted Bruce.
When Miranda Tate was put in charge of the company instead, Daggett complained to Bane about it and Bane told Daggett's assistant, Phillip Stryver, to wait outside. Bane then grabbed Daggett once Stryver was gone, and said, "I'm necessary evil," right before breaking Daggett's neck. Officer John Blake later told Jim Gordon in the hospital that Daggett's body was found in a dumpster.
