Nothing says more than a
throwaway line uttered very nonchalantly by Cameron's model girlfriend Sonja (Shalom Harlow),
after she says she has to prepare for a show: «I have to shower and vomit.»
So much of what actually works here comes from little looks, an occasional
throwaway line in what seems to be a screenplay that left plenty of room for the two lead actors to improvise jokes to mixed effect, and the situations that are far shorter than the majority of scenes, like when the son takes his mother to the Grand Canyon
after she has spent the entire trip saying she wants to see it.
