The third and final season ofDerry Girlsdebuted on April 12, and the first episode had an exciting surprise for viewers of the show. Northern Irish actor,Liam Neeson, made an unexpected cameo on the show, playing a very deadpan Chief Constable Byers.

Derry Girlsfollows five Northern Irish teenagers in the 1990s, towards the end of the Northern Ireland conflict, through their exploits and many misadventures in Derry. The five friends often find themselves in absurd and crazy situations, which was the case when they ran into Neeson’s character. Chief Constable Byers is introduced when he is questioning the girls after they attempt to break into their school to find out their GCSE results. As these things go, they inadvertently help a pair of thieves stage a robbery of computer equipment in the process, leading to their arrest.

However, it wasKevin McAleer’s Colm McCool that proved too much for Chief Constable Byers.
