Once you get past the intimidating-looking name (hint: it rhymes with tonal) and his impressive pedigree (his father is well-known Irish actor Brendan Gleeson), it's easy to see why the multi-talented Domhnall Gleeson has become so successful. Though he initially resisted becoming an actor, early appearances in two U.K. miniseries, "Rebel Heart" (BBC, 2001) and "The Last Furlong" (RTE, 2005), eventually gave way to roles in plays such as David Mamet's "American Buffalo" and Martin McDonagh's "The Lieutenant of Inishmore." Projects like his 2009 self-written directorial debut, the short film "What Will Survive Us," and his stint as a writer and performer on the Irish sketch-comedy series "Your Bad Self" (RTE, 2010) fueled Gleeson's creativity, while his role as Bill Weasley in the epic "Harry Potter and the Deathly Hallows: Part 1" (2010) and "Part 2" (2011), along with memorable performances in "Never Let Me Go" (2010) and "True Grit" (2010), provided international exposure. After a strong 2012 that found him in both "Shadow Dancer" and "Anna Karenina," it seemed like the once-reluctant Domhnall Gleeson finally became comfortable with being an actor. That quickly led to a string of even higher-profile roles, including a starring role in science fiction love story "Ex Machina" (2015) and the period drama "Brooklyn" (2015), as well as key supporting roles in Alejandro González Iñárritu's "The Revenant" (2015), Darren Aronofsky's "mother!" (2017), Doug Liman's "American Made" (2017) and both "Star Wars: The Force Awakens" (2015) and "Star Wars: The Last Jedi" (2017).
