10pm, BBC FourTheJapanese comedian Tomoaki Hamatsu thought he was going to an audition. But when a producer asked him to strip naked and carry out a series of challenges, it turned out he wasn’t being told the truth. In fact, he was being filmed and broadcast to 15 million people.

Walking and Talking (Nicole Holofcener, 1996), 1.15am, Film4Between television assignments, Nicole Holofcener makes witty, perceptive films about women’s lives, usually set in New York. This 1996 drama was her first, and follows best friends from childhood Amelia (Catherine Keener) and Laura (Anne Heche) as their bond is stress-tested by Laura’s engagement to her boyfriend, Frank (Todd Field).
