Tuesday night, BBC 4: Derek Jacobi turning in one of the greatest ever individual TV performances in 'I Claudius', still fresh and brilliant after 40 years.
Monday night, ITV: Derek Jacobi, in the cringe-making new sitcom Vicious, playing one of a pair of stereotype screamingly camp bitchy gays alongside Ian McKellen, amid canned laughter, stock characters and lowest common denominator entertainment of all kinds. The Daily Fail liked it, needless to add.
How have the mighty fallen.
