If there is one thing Bob Costas loves as much as baseball, it's watching movies. The limited series "Costas at the Movies" combines the sports broadcaster's two entertainment-related passions, as each 30-minute episode delves into a baseball movie and features Costas interviewing the actors, actresses and directors who helped make the films special. Guests include actor Tommy Lee Jones and director Ron Shelton ("Cobb"), actress Tatum O'Neal ("Bad News Bears"), actress Geena Davis and director Penny Marshall ("A League of Their Own"), and directors John Sayles ("Eight Men Out") and Barry Levinson ("The Natural").
