Starring:

• Billy Dee Williams
• Jack Warden
• Bernie Casey
• Shelley Fabares

IMDB.com
It is a story of 2 men--Gale and Brian...2 unlikely people to become the best of friends...The actors were well cast--James Caan and Billy Dee Sayers fit their roles to a tee. It is a film not only of friendship but also of love...a film of triumph of the human spirit. It is a story that transcends time and overcomes barriers to relationships, whatever they might be--racial, religious, or political. It challenges the viewer to assess his/her own prejudices and why it must be overcome. It is as timely as it was when it was first shown. A real winner but be prepared with a box of Kleenex when watching this very touching film.
