A tutorial overview is presented concerning the problem of the liquid-vapor critical point of physically adsorbed films. Emphasis is placed on the behavior of atoms and spherical molecules adsorbed on graphite. The critical temperatures are interpreted in terms of a theory based on "realistic" interactions. These deviate from Lennard-Jones form and include the substrate-mediated contribution. The role of the periodic potential in suppressing a critical point is discussed briefly.
