Empire veteran and all-round film journalism legend Helen O'Hara stops by for a very special Radio 1's Screen Time episode celebrating Lisa McGee's beloved Channel 4 sitcom, Derry Girls, which recently aired its final episode. Plus, as a bonus extra that's a must-listen for all fans of the show, Ali also got to speak to Erin Quinn herself, Saoirse-Monica Jackson, about how the show changed her life, how she got the gig and her favourite moments over the years.
