Several proponents of the interventionist theory of causation have recently argued for a neo-Russellian account of causation. The article discusses two strategies for interventionists to be neo-Russellians. First, I argue that the open systems argument---the main argument for a neo-Russellian account advocated by interventionists---fails. Second, I explore and discuss an alternative for interventionists who wish to be neo-Russellians: the statistical--mechanical account. Although the latter account is an attractive alternative, it is argued that interventionists are not able to adopt it straightforwardly. Hence, to be neo-Russellians remains a challenge for interventionists
