Who’s appeared on Christmas Day on BBC1 more than anyone else? Well, there’s The Queen, obviously, and people like Brucie, but surely quite high up the list must be Tim Allen, given his starring roles in the Toy Story films and indeed all three Santa Clause movies, at least one of which has been on the 25th for most of the last two decades or so. He’s a big star in the US, though less so as himself here in the UK, and indeed we recall his stand-up show being shown on Channel Four in 1993 and scoring a rare example of a primetime audience so low it was rounded down to zero, and despite persisting for a long time, they could never make Home Improvement a hit. Better find out what his appeal is, then.
