Settle in for a supersized season premiere of The Graham Norton Show.

Review by Gabrielle Tozer.

Hollywood stars Justin Timberlake and Anna Kendrick drop by to help Graham Norton kick off his 20th season of The Graham Norton Show.

While there’s a bit of chatter about their new animated kids’ flick, Trolls, the real fun is in watching JT join the audience for a daggy dance-off.

Harry Potter star Daniel Radcliffe also swings past the couch for a chinwag and a giggle.

The actor reveals he had a rather awkward encounter as a child when he met US President-elect Donald Trump many years ago while promoting the Harry Potter movies.

Plus, music superstar Robbie Williams delivers a show-stopping performance of his latest single.

Graham always delivers an A+ line-up. And, with a stellar crew like this one, it looks like he’s continuing to raise the bar in 2017.
