Luther back with 5m
BBC1’s detective brand Luther returned on Tuesday with its lowest series debut audience to date.
Luther (BBC1) 9pm-10pm
The crime drama, starring Idris Elba, launched in a blaze of publicity, but it failed to convert into a winning audience.
Its audience of 5m was 600k below 2011’s series opener, which drew 5.6m (25.16%). The first run launched with 5.64m (23.78%) the year before.
The programme also dipped under BBC1’s slot average of 5.19m (21.91%) for the past 12 months, according to overnight Barb figures supplied by Attentional.
It also lost half a million viewers over the period it was on air, opening with 5.09m (22.3%) between 9pm and 9.05pm, before bowing out with 4.59m (20.37%) in its final five minutes.
Despite the relative underperformance, Luther was still victorious in the 9pm slot, securing nearly 2m more viewers than its closest terrestrial rival.
