John Barrowman
The 49-year-old actor has admitted he wants to reprise his role as Captain Jack Harkness in the hit television series, and has teased he is heading to Cardiff, Wales, where the sci-fi drama is filmed for a secret project.
Speaking on BBC's 'The One Show' about a possible comeback, he said: "I'd love to, keep watching. Keep watching, I've love to! I don't know! It's not up to me ... but keep watching!"
Barrowman made his first appearance in 'Doctor Who' in 2005, and then in spin-off show 'Torchwood', and continued to make cameos in both programmes until 2013.
Speaking about his next project, he said: "I will be back in Cardiff in about a week and a half ... but I'm not telling you what for!"
Last year, showrunner Steven Moffat brought back Alex Kingston's character River Song for the Christmas special, and it is hoped the writer will bring Barrowman in for 2016's festive adventure or next year's new series, his last in charge of the programme until he hands control to 'Broadchurch' creator Chris Chibnall.
Peter Capaldi currently flies the TARDIS as the titular Time Lord.
