In the 1970 film "Cromwell", Michael Jayston plays Ireton as a subtle but well-meaning manipulator who hates Charles I and pushes Cromwell into actions, which Cromwell at first considers neither desirable nor possible, but then pursues all the way. This version of Ireton is ready to denounce the king and plunge England into civil war before Cromwell becomes convinced that this is a necessary step. In the film, Cromwell and he are also among the five members whom Charles I attempts to arrest on the eve of the war (when in fact they were not), and after the King is executed, is upbraided by Cromwell as being too ambitious. No mention is made in the film of Ireton marrying Cromwell's daughter.
