Finn Eces (Finneces, Finegas, Finnegas) is a legendary Irish poet and sage, according to the Fenian Cycle of Irish mythology. He is the teacher of Fionn mac Cumhaill, according to the tale The Boyhood Deeds of Fionn. For years he tries to catch the Salmon of Wisdom, a fish that will grant all the world's knowledge to whoever eats it. He is unsuccessful until he takes the young Fionn as his charge, but when Fionn cooks for him, he burns his thumb and puts it in his mouth. He therefore receives the fish's knowledge, which he can access by putting his thumb in his mouth again.
Nuada is referred to in some sources as Nuadu Finn-Éces, and certain authors suggest that the story of Fionn Mac Cumhall and the salmon of knowledge is related to the cult of Nodens or Nuada, which was introduced into the Boyne Valley mythological corpus some time in the early centuries BC. Nuada was integrated into Fenian lore as an ancestor of Fionn, the name Finn-Ecas meaning "Finn the Seer."
Finn (pl. Finns) is commonly used to refer to a member of the Finn ethnic group or a citizen of Finland.
Finn (originally designated Stormtrooper FN-2187) is one of the main protagonists in the 2015 film Star Wars: The Force Awakens. In the film, he is a Stormtrooper for the First Order who flees after being shocked by their cruelty in his first combat mission before joining the fight against them. He is played by English actor John Boyega.
The idea for the character Finn came from Star Wars screenwriter Lawrence Kasdan. Colleague Michael Arndt, who had prepared an early draft of The Force Awakens, revealed:
For the roles of Finn and other new Star Wars characters for The Force Awakens, director J. J. Abrams intentionally looked for unknown actors, as he wanted audiences “to meet these characters [in the film] and not feel like it’s him from that thing, it’s her from that thing.” Boyega, who had impressed Abrams in his debut role in British sci-fi film Attack the Block (2011), was invited to audition for the role of Finn, a process which lasted seven months before he was finally cast.Kathleen Kennedy, one of the producers of The Force Awakens, stated:
Finn the human (Real name: Finn Mertens), known as Finn to most characters is, along with Jake the Dog, a fictional character and one of the main cast of the American animated television series Adventure Time created by Pendleton Ward. He is voiced by Jeremy Shada in most appearances. The character made his debut in the original pilot, wherein he was named Pen and voiced by Zack Shada, Jeremy's older brother.
The character has been met with largely positive critical reception.
