For this very special episode of BBC Radio 1's Screen Time, Ali got to visit Framestore, the legendary visual effects house where - amongst other things - the preposterously charming Paddington is brought to life. So that bathtub down the stairs scene? The barbershop chicanery? The hair-raising train sequence from the end of Paddington 2? These guys. Speaking to producer Rosie Alison, VFX animation director Pablo Grillo and our new director Dougal Wilson (stepping into the shoes of Paul King, the man behind the first two Paddington films), Ali found out more about how everyone's favourite marmalade-loving bear ends up on our screens, makes us cry and leaves us really hankering for a particular kind of sandwich.
