Much like our interview with The Rock and Kevin Hart, Ali Plumb's chat with Jack Black and Karen Gillan went off the rails in a delightful, musical, thoroughly Christmassy way. Expect singing, silliness and STRONG LANGUAGE. Got to be clear about that. #Jumanji #JackBlack #KarenGillan Listen to Ali Plumb's podcast, Radio 1's Screen Time, by downloading the BBC Sounds app (https://www.bbc.co.uk/sounds/series/p02r4zfx) or watch Movies with Ali Plumb on BBC iPlayer. -- Official Channel of BBC Radio 1 Here you can find your favourite live performances, the biggest movie stars, amazing interviews and more...
