Storytellers drawn to boxing’s inherent drama invariably find redemption at its soul and conflict as its heart. Ring tales are on a roll thanks to Mark Wahlberg’s Oscar-winning film The Fighter and FX’s series, “Lights Out,” (the series finale airs next Tuesday, April 5 at 9 p.m.). Although FX recently announced it has decided not to renew the show for a second season, the show received favorable reviews from critics while generating more than usual interest locally, as it stars former home boy Holt McCallany in the breakout role of the fictitious Patrick “Lights” Leary, an ex-heavyweight champ attempting a comeback. McCallany grew up in Omaha, the eldest of two rambunctious sons of Omaha native and legendary New York musical theater actress and cabaret singer Julie Wilson, and the late Irish American actor/producer Michael McAloney. Like his hard knocks character, McCallany was truant and quick to fight. He was expelled from Creighton Prep. He says most of the “unsavory crew” he ran with outside school “wound up in jail.” At 14, he ran away from home — flush with the winnings from a poker game — to try to make it as an actor in Los Angeles. “I was a very rebellious and a very ambitious kid,” he says. In the spirit of second chances linking real life to fiction, he got some tough love at a boarding school in Ireland and returned to graduate from Prep in 1981, a year behind Alexander Payne, whom he hopes to work with in the future. McCallany, who’s returning to Omaha for his class’s 30th reunion in July, appreciates the school not giving up on him. “I got kicked out but they eventually took me back, and they didn’t have to do that. Near my graduation I said to one of the priests, ‘Why did you guys take me back?’ and he said, ‘Because we believe in your talent, Holt. We see a lot of boys come through here and we believe you can be one of the first millionaires out of your class and a good alumnus.’ When you’re a kid you take that stuff to heart and it kind of stays with you, and if you believe it, other people will believe it about you, too.” Tragedy struck when his troubled kid brother died at 26 in search of another fix. It’s a path Holt might have taken if not for finding his passion in acting. “I felt like I had a calling. My brother didn’t have that, and my brother’s dead now, and I can tell you a lot of the pain and suffering he went through is related to this subject. When you don’t know what it is you want to be and you’re lost and you’re floundering and you’re going from job to job and kicking around and nothing really works out, it’s a very dispiriting place to be. It can lead to substance abuse and a lot of negative things.” In the show, Leary’s a devoted husband and father trying to rise above boxing’s dirty compromises, but he and his younger brother get sullied in the process. McCallany, who infuses Lights with his own mix of macho and sensitivity, is the proverbial “overnight sensation.” He’s spent 25 years as a journeyman working actor in film ( Three Kings ) and TV ( Law & Order ), mostly as a supporting player, all the while honing his craft — preparing for when opportunity knocked. Everyone from co-star Stacy Keach, as his trainer-father, to series executive producer Warren Leight to McCallany himself says this is a part he was born to play. Why? Start with his passion for The Sweet Science. “Boxing was my first love, and way back when I was a teenage boy in Omaha. My brother won the Golden Gloves. We had an explosive sort of relationship, he and I. We would often get into fistfights and all of a sudden he was getting really good.” As for himself, McCallany’s a gym rat. He’s logged countless hours sparring — “sometimes those turn into real wars” — and training with pros. He appeared in the boxing pics Fight Club and Tyson . He’s steeped in boxing lore. He brought in his friend, world-class trainer Teddy Atlas, as technical adviser on Lights Out . The pains taken to get things right have won the show high praise. The only critics who matter to McCallany are pugilists. “The response from the boxing community has been really positive,” he says. “There are a lot of similarities I find between boxing and acting,” he says. “In the theater the curtain goes up at 8 and the audience is in their seats and you’ve got to come out and give a performance, and it’s similar in boxing — there’s an appointed day and appointed time when you know people are going to be there ringside and it’s time for you to come out and perform.” In both arenas, nerves must be harnessed. “The anxiety is your friend,” he says. “That’s what’s going to ensure you’re going to do what you’re trained to do and, as Ernest Hemingway said, ‘remain graceful under pressure,’ which is really what it’s about.” As much as he admires great boxing films he says “Lights Out” is not constrained by the limits of biography or a two-hour framework. “We have all of this time to explore in rich detail a boxer’s life and his relationships and his psychology,” he says. “With this character the writers and I have the freedom to really create and really see where this journey is going to take us, and that’s very exciting. I can’t tell you exactly what’s going to happen in season two because I’m not sure, and I promise you they’re not sure either. That’s what’s different.” While they’ll be no second season now, McCallany’s up for a part in the next Batman installment and has a script in play with Lifetime.
