John Krasinski, Michael B Jordan have discussed Jack Ryan-John Clark crossover

Tom Clancy has written dozens of bestsellers over the years, spawning countless franchises. But the two characters he is best known for--Jack Ryan and John Clark--share the same fictional universe. When asked about any insider knowledge on how far Jack Ryan is planned to go, John says, “As far as how long this goes, right now we have only shot four seasons and it looks like that would be the end of the series. Another of Tom Clancy’s popular characters from the Ryanverse--John Clark--made an appearance in last year’s film Without Remorse. The third season of Jack Ryan also stars Wendell Pierce, Michael Kelly, Betty Gabriel, and Peter Guinness.
