Farrell had small parts in television shows and films, including the BBC drama Ballykissangel in 1998 and his film debut in Tim Roth's The War Zone. Then in 2000, he was cast in the lead role of Private Roland Bozz in Tigerland, an American film directed by Joel Schumacher. Farrell's next American films, American Outlaws (2001) and Hart's War (2002), were not commercially successful, but his 2003 films, including Phone Booth, S.W.A.T., and The Recruit were well-received box office successes. Although he has a pronounced Irish accent, Farrell uses an American accent in some of his films including American Outlaws and his breakthrough role, Tigerland. Farrell is also a proven supporting actor, given his performances as an ambitious cop who chases after a potential criminal, played by actor Tom Cruise in Minority Report (2002), and as the skilled villain Bullseye in Daredevil (2003). The character of Bullseye is that of an assassin with perfect accuracy and deep-rooted pride of it. Farrell was attached to this role in December 2001, though initially he was considered for the lead role as Matt Murdock, aka Daredevil, until Ben Affleck signed. Farrell was encouraged to keep his Irish accent as this version of Bullseye is from Ireland. Farrell had to read into Frank Miller's Daredevil comics to understand Bullseye "because the expression on the character's faces in the comic books, and just the way they move sometimes, and the exaggerations of the character I'm playing he's so over-the-top that you do draw from that. But it's not exactly a character you can do method acting for... you know, running around New York killing people with paper clips."
