VIDEO : Harvey Keitel: Hey E*Trade, Deal's a Deal Gimme My Cash

Harvey Keitel played "The Wolf" for E*Trade -- swooping in to save its ass in a commercial series, only to have the company yank a $1.5 million deal out from under him ... according to his lawsuit.
Keitel says E*Trade came to him in early 2014 ... desperate to land a new spokesman, after Christopher Walken turned them down twice. Negotiations were fast and furious, and they agreed on a 3 commercial deal -- he says the company sent him the contract, and he accepted the terms.
