Michael B. Jordan's Rainbow Six movie is the perfect opportunity to bring back Harrison Ford's Jack Ryan. Tom Clancy creation Ryan has been billed as something of an American everyman version of James Bond. That descriptor shouldn't imply Ryan hasn't been involved in his share of dangerous/potentially world-ending events though. Ryan's fortunes in live-action have been somewhat mixed because despite none of his movies being outright flops, audiences don't have a definitive version of the CIA analyst in mind. Jack Ryan has been played by Alec Baldwin, Chris Pine, Ben Affleck and Harrison Ford.
