The finale of Derry Girls aired this week, and we are looking back at some of the famous faces who turned up in season 3 of Derry Girls.
'The Big Fella' was his codename on set, but in the show he played a policeman questioning the gang after a suspected break in.
He also appeared in the final episode in the midst of the Good Friday Agreement referendum.
Damien of BBC fame played a plumber, who sparked Mary's interest in going back to school.
Serena, famous for her Mammy Banter videos, is an author and comedian from Derry. She played an RUC officer who arrested the gang, and said being in the show was "a dream come true."
Amy joined the cast for the third episode of the season. She was hilarious as an inappropriate train station clerk, who made things awkward for Claire and Sister Michael.
The sketch artist and Irish Twitter icon Michael Fry got into a row with the Derry Girls on the train to Portrush.
The Fair City actress stepped into the part of an old friend of Mary and Sarah, who they can't quite remember.
The Game of Thrones actor was the psychic Carlos Santini. While the family felt ripped off by their reading, he did prove useful in locating Grandad Joe's missing electric razor!
A special guest joined the episode five flashback, show creator Lisa McGee's husband Tobias Beer. He played the silent surgeon and dad of Jenny Joyce.
Emmet joined in episode five, and challenged James to a fight outside for Fat Boy Slim tickets. Not exactly Kin or Peaky Blinders, but he was definitely intimidating.
The Scottish DJ and boyfriend of Saoirse Monica Jackson was the one to throw the gang out of the Fat Boy Slim concert 'for fighting.'
National treasure Sinead Burke showed up in episode six as the TV host who took pity on Michelle.
The final scene of the last ever episode, shows the letter the gang sent Chelsea Clinton found its way to her. What a special ending!
We are so sad to see the Derry Girls go.
