Mastermind

7.30PM, BBC2

Six trepidatious contenders take their place in the notorious black chair for the series final, as John Humphrys fires the questions. Subjects are the history of Leningrad, US sitcom Seinfeld, the life and work of Billy Wilder, architect Inigo Jones, the short films of Laurel and Hardy, and the rather longer ones of Alfred Hitchcock.
