  We investigate the behavior of the collective excitations of adsorbed $^4$He
in an ordered hexagonal mesopore, examining the crossover from a thin film to a
confined fluid. Here we present the inelastic scattering results as a function
of filling at constant temperature. We find a monotonic transition of the maxon
excitation as a function of filling. This has been interpreted as corresponding
to an increasing density of the adsorbed helium, which approaches the bulk
value as filling increases. The roton minimum exhibits a more complicated
behavior that does not monotonically approach bulk values as filling increases.
The full pore scattering resembles the bulk liquid accompanied by a layer mode.
The maxon and roton scattering, taken together, at intermediate fillings does
not correspond to a single bulk liquid dispersion at negative, low, or high
pressure.
