10 Reasons You'll Love Dónal Finn as Mat Cauthon

Observations from his Live Performance in Sing Street and What It Means for Season 2 of The Wheel of Time

This article contains spoilers Sing Street and for the Wheel of Time book series through Fires of Heaven.

One of the greatest mysteries of Season 2 of The Wheel of Time is how the recasting of Mat Cauthon will play out, with Dónal Finn replacing Barney Harris in the role. Fans knew about the recasting before Season 1 even aired, but information about Dónal is scarce, and he's rarely seen on social media.

Aside from a couple short quotes from Rafe Judkins (via Empire and Deadline) and a few glimpses from Instagram darlings Priyanka Bose and Madeleine Madden, WoT fandom has seen no news or official word on Dónal Finn from Prime Video—no behind-the-scenes glimpses, no interviews or articles. It became an inside joke that fans would only ever see the Irish actor in cropped sections of blurry photos.

Speculation, of course, runs wild about the reasons for the dearth of Dónal. Is it to build suspense? To avoid reopening old wounds or upsetting newer fans who may not know about the casting change? To gear up for a big Mat reveal in the teaser trailer? (Please drop said teaser trailer at the NYCC panel next week.)

As eager fans try to predict what Dónal might be like as Mat, there isn't much to go on. So far, the most Mat-like footage of Dónal is from an interview for the play, Chasing Bono, which features a glimpse of Dónal’s dimples and mischievous smile.

Donal, in the foreground, has curly dark hair and a charming smile. The subtitle reads "My doppelganger is my best mate, Aina, from home."

But Dónal was 4 years younger in that interview and looks more like the Mat who just released some badgers onto the village green—not exactly the smile that screams you’ve suffered childhood neglect from messed up parents and are now about to resort to dark means to get back to your sisters.

Just when it seemed like all hope was gone that present-day Dónal would make an appearance before Episode 1 of Season 2, WotSeries's expert creeper, Geeky Eri, reported that he was performing in the musical Sing Street (based on the 2016 movie) at the Huntington Theatre Company in Boston.

To anyone living in the near vicinity of Boston, the message was clear: go find Dónal and report back to the poor, deprived fandom with whatever drops of information you can gather.

So it was that my friend and fellow Dusty Wheel moderator, Anas, joined me in tracking down the elusive Dónal Finn last Tuesday night. The two of us are always down to do elaborately nice things for the fandom, so this kind of adventure was totally on brand for us. It was for research, we said.

The night turned out better than we ever dreamed, and not just because of Dónal's performance. After the show, we found ourselves shaking hands and having a pleasant conversation with the actor, who, despite our fantasies of him being surrounded by bodyguards holding off a hoard of fans, was just a regular guy, heading home from work.

Donal Finn's signature in cursive writing is on the right hand side of the program, and the Sharpie marker he used is clipped onto the front of the program.

I once believed I would never get over the loss of Barney Harris and that the recasting would be jarring. I’ve participated in many a discussion with others who have similar worries as to what the change in such a central character might mean for The Wheel of Time.

I am here to tell you that Dónal Finn wiped every single one of those worries away. His performance was absolutely delightful, stunning at times, and extremely promising for Season 2 Mat.

I haven’t reviewed Dónal’s previous work, but based on his performance in Sing Street and the short interaction we had with him, I am now confident that he will nail the role and charm the fandom. I adore Barney Harris's Mat, but I am 100% sold on Dónal and ready to move on.

While I can’t guarantee that anyone else (except Anas) will feel the same, here’s 10 reasons I think you will love Dónal Finn in The Wheel of Time.

1. His Portrayal of Mat-like Qualities

Sing Street takes place in 1980's Dublin and follows the adventures of Conor Lawlor (Adam Bregman), a teenage boy who forms a band to impress a girl. It’s a coming-of-age story about music as an escape from the realities of family conflict and high school bullying. Dónal Finn plays Conor’s older brother and musical mentor, Brendan.

Brendan has a lot in common with Mat. In a nutshell, Brendan's character arc is that he struggles with darkness and addiction which isolate him from others, but he uses humor and charm to get by. Eventually he overcomes his problems in order to support his more serious brother before finally accepting his own talents in a victorious grand finale. Sound familiar?

Brendan spends most of his time smoking weed on the couch and listening to music, seemingly content, much like Mat, to help from the sidelines yet coming through when it really counts. And while he doesn’t get into any mischief himself, Brendan readily encourages his brother to do so, persuading him to do whatever it takes to stand up to bullies, get the girl, and live his dreams.

As Brendan pushes aside his own mental health challenges to support his brother, Dónal skillfully conveys that Brendan is feeling one thing while showing another. This suggests that Dónal will be able to bring nuance to Mat’s many layers of emotions, even when he’s lying to himself.

At the end of the show, Brendan finally peels himself off the couch and does a very Mat-like thing: reluctantly sacrifices his own comfort in order to help others. It has the feel of Mat doing what it takes to protect the vulnerable, even if it means inconveniencing himself.

So, can Dónal play Mat? In Sing Street, he basically did.

2. His Range

Given the similarities between Brendan and Mat, and the realities of the entertainment industry, it's likely that Dónal was cast for his ability to play that type of role. But Dónal has the range to be so much more than the troubled but charismatic prankster rogue.

The second act of Sing Street reveals Brendan's softer, more vulnerable side. In a particularly memorable monologue, Brendan describes his unhappy mother’s habit of sitting outside in the sun until it goes behind a tree in their yard.

Dónal delivers this speech with just the right amount of sentimentality without going overboard. His eyes glisten with a hint of tears as he stares up into the stage lights, looking, as the character Raphina would say, "happy-sad."

In just a couple short hours, Dónal proves he has the range to do just about anything, from a big, screaming breakdown of rage and regret (“Once, I was a f***ing jet engine!”) to a quiet, painful moment (“I’ve never heard the house so quiet. It’s...not good”).

What this means for The Wheel of Time is that Dónal is capable of bringing depth and complexity to Mat's character—no easy feat, as we know from Brandon Sanderson's comments about the difficulty of writing Mat.

3. His Physicality

A great stage actor is someone who can take up space and use the entire stage as their playground, making big movements that read to the audience.

Dónal has mastered that skill and knows how to fully embody a character consistently, even when he isn’t the main focus of a scene. Whether it was delivering a passionate monologue at the precipice of the stage or sitting at a table with family in the background, Dónal’s physicality always entertained.

Then there was the The Couch. During a musical interlude between scenes, Brendan, high AF, stumbles, tumbles, and slides all over a 1980’s plaid sofa while his sister, Anne (Alexa Xioufaridou Moster), attempts to take a joint away from him.

Dónal probably has some dance training, based on the graceful and purposeful way he moves, playing off both his sister and the couch, which moves and rotates along with the two of them, almost like a third dancer.

Anne is visibly frustrated and concerned for her brother, but Dónal’s languid stoner smile is so fetching, you kind of hope Brendan gets to keep the joint. In fact, you wish Anne would just leave Brendan alone with The Couch, because Dónal was really having a moment with it.

The dance concludes with Dónal in a melting, full body slide from the top edge of the sofa, down the cushions and onto the floor that can only be described as HOT. You can try listening to my poor man’s description of The Couch here, but if you need your mind blown, I would recommend getting a ticket to Sing Street before it closes.

While Dónal won’t necessarily need to make stage-sized movements on screen, Mat needs to move more than any of the other main boys. Perrin is slow, Rand is uptight, but Mat is quick, slippery, and fluid. He needs the physicality to dance with tavern servers, run from pursuers, escape from tricky situations, toss dice with flair, and, most importantly, fight.
