Leading vs. Supporting Categories in 1999 …
IMO Haley Joel Osment was a co-lead along with Bruce Willis in The Sixth Sense. The movie is his story and he is in the entire thing. I think this is a case of not wanting to put a juvenile in competition in the lead category. We saw this years before with Tatum O’Neal in Paper Moon. Toni Collette is supporting.
I saw Being John Malkovich again not long ago and thought Catherine Keener is the female lead. Oscar had her in the supporting category but she is never far from what’s going on in this film. I also thought John Cusack and John Malkovich are the male co-leads. Cameron Diaz is supporting.
Sarah Polley is the lead actress in Go.
Reese Witherspoon is supporting in Election. Matthew Broderick is the male lead.
Al Pacino and Russell Crowe are co-leads in The insider.
