Professor T (2027)

Professor T itself is proving to have long legs too, with a fifth season coming soon – and the future beyond that is looking bright too, as revealed by Miller himself on The One Show last night.
"It is coming back... We've got season 5 that will hopefully be coming out in the autumn," he began. "I mean, spoiler alert, we're actually working on season 6. It's a very exciting situation to be in."
