Writer and creator Lisa McGee and director Michael Lennox shared the details of how the 'Taken' actor ended up in the 'Londonderry RUC Station'.
At a Q&A in the Guildhall after the show's premiere in Derry last week, Michael Lennox said it was actually Dame Helen Mirren who told Neeson to watch Derry Girls.
Both Lisa and Michael said that he explained he was "a fan of the show" and they had been calling him 'The Big Fella' to try and keep his identity a secret until the first episode aired on Tuesday.
She also joked about the experience being "really, really scary" and hiding from Liam Neeson on set until she said, "he called for me".
Liam Neeson and Helen Mirren dated in the late 1980s and lived together for four years before they broke up.
