Leading vs. Supporting Categories in 1989 …
IMO Martin Landau was the lead in Crimes and Misdemeanors. It is Landau’s story all the way. Perhaps his reputation as a character actor and the producer’s desire to put him in an easier category lead him to be dubbed supporting.
I am putting Jack Nicholson in the supporting category for Batman even though he has an extraordinary amount of screen time. This is an instance where screen time isn’t everything.
Gary Farmer and A. Martinez are co-leads in Powwow Highway.
James Spader and Andie MacDowell are the two leads in sex, lies and videotape.
Nick Nolte and Rosanne Arquette are leads in New York Stories.
Jeff And Beau Bridges and Michelle Pfeiffer are all leads in The Fabulous Baker Boys.
Matt Dillon and Kelly Lynch are the two leads in Drugstore Cowboy.
Tom Conti is supporting in Shirley Valentine.
