Shimmying into Graham's studio tonight is Hayden Panettiere, one-time self-mending heroine of cult US sci-fi drama Heroes, now strutting her diamanté chic in slick US country soap Nashville. Also dropping in for a chat is Dan Stevens, Downton Abbey's Matthew Crawley - one of the few decent chaps in the period drama - who was controversially bumped off on Christmas Day. Just after he'd become a new dad, too. Such a harsh way to write out a character. The nation was not amused as we choked on our figgy pudding.

A rotating line-up of hosts used to make HIGNFY one of television's most unpredictable panel shows, but we're afraid to say that the show's become a little stale of late - as much as we love them, it'd be nice to have a break from David Mitchell, Jack Dee, Jo Brand et al. The last time we had a left-field choice of host was 2010's Damian Lewis, so we're excited to see how Downton Abbey star Dan Stevens performs in the hot seat this Friday.
