Tune In Tonight: TV movie blends reality and fiction

In a case of made-for-TV casting magic, a network star plays a cable star in an adaptation of a book based on the cable star’s own life story. Did I mention that the cable star also produced the movie? If it were up to me, it would be Brad Garrett in “The Bill O’Reilly Story,” but we’ll have to settle for Jennie Garth (“Beverly Hills, 90210”) playing cable’s legal scourge Nancy Grace as a young assistant district attorney in “The Eleventh Victim” (7 p.m. Saturday, Lifetime).

Loosely based on Grace’s own life and career, “Victim” follows Hailey Dean (Garth), a fictional stand-in for the television personality. While prosecuting a notorious serial killer, the defendant physically assaults her in court. After that trauma, Dean relocates to New York to restart life as a therapist, only to find her patients dying one-by-one — in a manner similar to the method of the creep she helped put behind bars. Colin Cunningham and Los Angeles Lakers star Metta World Peace co-star.

• Comic Larry Wilmore (“The Daily Show”) heads to Florida to examine the swing state’s exotic, religious and economic conditions the weekend before that state’s crucial role in the 2012 presidential election. “Larry Wilmore’s Race, Religion and Sex in Florida” (9 p.m. Saturday, Showtime) includes comedians Paul Rodriguez and Moshe Kasher, Republican strategist Ron Christie and Current TV’s Ana Kasparian in a town hall discussion of Florida’s very peculiar blend of cultures.
