This segment has the same title, but is unrelated to, two different American films, which, in turn, have no relation to each other. The first was a 1983 comedy about an "invisible man" directed by Bruce Malmuth and starring Steve Guttenberg; the other was a 2001 film nor directed by Joel Coen and starring Billy Bob Thornton.
There is also a French thriller movie from 1987 with that title; it's directed by René Féret, and based on Roderick MacLeish's 1976 novel of the same title. In addition, there are two other novels (1937 by Anthony Gilbert, 1989 by Pat Barker) with the same title. These are all unrelated (or at least not directly related) to this episode.
