The two earlier comments seem to be for the other movie Last Night (1998/I) directed by Don McKellar, and not this movie Last Night (1998/II) directed by Neil Kinsella. They refer to characters and events that are in Last Night (1998/I) but are not listed as characters in Last Night (1998/II).
I tried to find out more about this movie, but it seems to have faded into obscurity, so I'm unable to even read a summary of it. One other cinema site even put Neil Kinsella as a director of Don McKellar's film, which is not the case in the credits I saw in McKellar's film.
Although this is not strictly a review of Kinsella's film, I do feel that my comment is more informative and useful than the two previous comments, because it is actually about this film. Sort of.
