Desilu (Bravo, 9-11 p.m.): Desi Arnaz came from a wealthy Cuban family that fled as Castro's revolution took over. He arrived in the US penniless, and though his accent aroused some animosity among studio heads, he made his mark in showbiz and was always grateful to his adopted country. He met Lucy in the movies, and the two built a television empire, Desilu Productions, which created the three-camera situation comedy, the police drama, and the medical drama. He had the business sense and foresight to see TV's potential, and she had the comedic talent. The affecting tale of their lost relationship is told with great insight by their daughter, Lucie Arnaz, as many of the TV industry's greatest stars underscore the importance of Desilu's unique contributions to the craft.
