You might not have heard of Aisling Franciosi yet, but it won't be long before you do. Trust. The up-and-coming actress has already starred in super-scary series The Fall alongside Jamie Dornan (we still can't work out if it's acceptable to fancy him in that show), as well as appearing in new 1950s-set BBC thriller Quirke (think Mad Men, but with a lot more murder) as the feisty Phoebe Griffin. We caught up with Aisling after her whirlwind trip to Cannes, promoting her latest film Jimmy's Hall, to talk 50s fashion, red-carpet rules and what Jamie D is like IRL.
