Second Thought reboots with terrific Thom Pain; WaterTower makes Irish stew of Inishmore.

Deconstruct the features of Dallas actor Steven Walters and it's hard to believe they constitute the attributes of a great stage performer. There's his voice: high, a little nasal, with a hint of Texas twang and audible hisses on sibilant consonants. There's his chin, strong but soft. His long nose curves downward toward thin lips. Pale brows and blond lashes frame gray-blue eyes. Walters is tall and slim, almost spindly, depending on how well his clothes are fitted for a role. And he has large hands with delicate fingers, which he often thrums against his legs during wordy speeches in plays.

It all works together somehow to make him fascinating to watch. Add those elements to his considerable acting skills and you understand why Walters right now is the most sought-after actor in his age range (late 20s) among the city's best professional theaters. Considered a leading man—and he can be exceedingly handsome, even with those thin lips—he's just come off a run of starring roles at Dallas Theater Center, where he played Prince Hal in Shakespeare's Henry IV last fall and had leads in two of the Beauty Plays in DTC's fine productions of that trilogy.

Now he's back as co-artistic director and actor at Second Thought Theatre, the small company he co-founded with other Baylor grads seven years ago and then left to act on TV's Chase and Friday Night Lights and to pitch screenplays in Los Angeles. In Second Thought's black box space at the Addison Theatre Centre (which also houses WaterTower Theatre), Walters is starring in the 70-minute monologue Thom Pain (based on nothing), writer Will Eno's strange, sardonic, one-sided conversation about the meaning of life.

Barefoot on a bare concrete floor, wearing a black suit, white shirt, skinny black tie and black-framed goon glasses, Walters does some brilliant talk-jazz with the dissonant chords of Eno's dialogue. His character, speaking directly to the audience in the 75-seat theater, is friendly one moment, hostile the next. Eno peppers the play with bursts of funny, unexpected exclamations. "Do you like magic?" Thom Pain asks at the top of the play. "I don't. Enough about me." And zip, he's onto the next topic. Relating a story about the love of his life, he recalls their first date: "'You've changed,' she said the night we met." And this, about the same girl: "She had a doggedness I found very fetching." Ba-dum-pum.

Pausing the verbal spew only a few times, Walters, sharply directed by Dallas Theater Center company member Matthew Gray, is careful not to indulge too long in the ups or the downs as Thom Pain rewinds again and again to stories from childhood and to moments from a broken romance that has shredded his character's confidence. Punctuating the barrage of dialogue are playwright Eno's bits of theatrical sleight of hand. An audience plant storms out halfway through, causing an eruption of profanities from Thom. Later, Thom pulls a small red box of raisins from his pocket and munches a few. "Picture whatever you want," Thom tells the crowd. "You are free." Until, that is, he forces someone to join him onstage, where he ignores the person, left sitting in a chair with eyes closed, until the play is nearly over.

Thom Pain (based on nothing) asks that theatergoers think—and not just about what they had or want to have for dinner, which is all so many new plays ask. Nothing goes as expected in this performance piece, and nothing is fully explained. Questions are asked, explicitly and implicitly: When does childhood end? How long does the torch stay lit for an old love? Why is Thom Pain not wearing any shoes? And is that glass of water at the back of the stage half full or half empty?

Walters, through all of it, stays in tune with the material and with his audience. Never has it been more tempting to answer back to a direct question from the stage—and Walters could probably work wonders with a moment like that if anyone were ever so bold as to speak up during this show. And never has there been a greater urge to hug a character who seems so distraught. Thom Pain is in pain for much of this play, but he's also eager to teach us things from the hard life lessons he's endured. Like, how to enjoy living in the moment, even if that moment is built around an old joke or a failed magic trick.

By the end of Thom Pain, Walters, dripping with sweat, is close to tears. He has gone places few actors are brave enough to go—namely, onto a bare stage, alone and unshod, to speak more lines than Hamlet—and he's put the audience under his spell.

WaterTower Theatre's artistic director Terry Martin has been itching to do Martin McDonagh's mordant Irish comedy The Lieutenant of Inishmore for a few seasons now. He's finally got it up on the big stage in Addison and even hired a nationally known special effects wizard, Steve Tolin, to carry out the play's various and numerous forms of bloodletting.

So why is this production so bloody bad?

Like one of the farcical episodes of The Sopranos ("Pine Barrens," for example), Inishmore is a tightly written, extremely violent comedy that juggles themes of life, death, stupidity and animal instinct. When the beloved pet cat of Padraic (Matt Moore), a notoriously mean Irish terrorist known for blowing up fish-and-chips shops, is found dead in the road in Padraic's home village of Inishmore, the man comes home to wreak some revenge. Padraic's father (Jason C. Kane) and a dim-witted neighbor boy (Tony Daussat), who thinks he squashed the kitty with his bike, bungle a cover-up. But Padraic, who can rip the toenails off a drug dealer (Matt Tolbert) with nary a wince, is intent on vigilante justice. As are a trio of other gun-wielding splinter-group terrorists (Clay Yocum, Evan Fuller, Ian Ferguson) who are hot on Padraic's tail and quick on their triggers. "Incidents like this that does put tourists off," Padraic's dad observes.

On opening night, the show was delayed for a bit when the complicated set by Christopher Pickart—a shabby cottage that rolls on and off—got stuck. But the whole production goes off the rails with slipshod timing, awkward casting and performances that ignore the comic potential in McDonagh's rhythmic, rural Irish patois. The plot gets knotty, but it's downright nutty how director Martin and his cast fail to nail the humor. Doesn't help that the actors' accents are all over the map—a map that seems to exclude Ireland.

Tolin, who has provided the explosions of blood and gunfire in nine previous productions of Inishmore around the country, delivers cinematic blood spills that are nauseatingly realistic. In a hail of bullets at the end of the play, the stage grows slick with red gore spurting from the skulls and chests of most of the actors. Too bad the rest of the show keeps shooting itself in the foot.
