BBC Three's award-winning Uncle is back in January for the final part of this comedy trilogy.It's been four years since man-child Andy (Nick Helm) forged an unlikely alliance with nerdy nephew Errol (Elliot Speller-Gillott). Suicidal and irresponsible, Andy cared only about having lost his girlfriend, and only looked after Errol after being blackmailed into it by chaotic sister Sam (Daisy Haggard).But a lot's changed since then. Through two series' of this buddy comedy with a difference, the pair have fought being kept apart, seen each other through heartbreak and triumphed together in a life or death song contest. And while they're not immune to the odd disagreement, they always have each other's back. Well, almost always.
