The big-collared comic returns for a third series of his family-friendly prime-time comedy. The show, which Hill himself admits has the flimsiest of set-ups, sees him and celebrity guests trying to fill a capsule to send to aliens in the hope to persuade them to not invade the world. Tonight he is joined by Alison Hammond, Martine McCutcheon, Les Dennis and Tom Courtenay. Among the highlights tonight include a race to see who can fall down the stairs the quickest, and attempts to belch down a drainpipe. Harry Hill’s Alien Fun Capsule is on ITV at 19.30.
