I'm Losing You (1998)

Nearing his 60th birthday, a movie producer discovers that he may have less than a year to live as a result of inoperable cancer. The effects of his disease take the toll on him and his distressed wife. However, his dysfunctional family are not told and their soap opera-ish life goes on. His son, a has-been actor, has to deal with a precocious daughter and a drug-addled ex-wife and sells AIDS patients insurance policies until he becomes attracted to one. His step-sister learns that her real father murdered her mother & then committed suicide.
