“You have to teach Liam Neeson!” the caller urged her. It was nobody less than Marcos Questas. “He does not know one step!” he continued. Well, an urgent request by Maestro Questas from LA means you don’t think twice!

On the receiving end of the line was Karina Romero, a veteran teacher among the New York Argentine tango community. She was trying to grasp what she had just heard: she had been asked to coach one of Hollywood’s biggest stars for an upcoming movie!

Questas, a sought-after choreographer for film and television (he worked on the Latin Grammy Awards), had a problem. He had been signed as the choreographer for a prominent tango scene in a high-profile spy thriller about the Watergate scandal by Peter Landsmann — Mark Felt: The Man Who Brought Down the White House. He had already started rehearsing the dance scene with Diane Lane, who plays Liam Neeson’s wife in the movie. But he urgently needed an instructor at the other end of the country in New York, where Neeson lives, to train him for his part. Questas knew about Karina Romero through Carlos Copello, the grand master of tango (Forever Tango, The Tango Lesson, Assassination Tango). Being part of Copello’s circle means being part of an exclusive network of tango professionals who can trust one another.

Karina Romero accepted. And Marcos Questas could for now, and until the shooting began, relax. Then he would see if the teacher in New York had been doing a good job.

But back in New York, Karina Romero could not have anticipated what was about to happen once she agreed. The wheels had already begun to spin and she had taken on a big responsibility. How did she prepare for coaching a film star for a big budget movie, I am curious to know? Karina takes a deep breath. Then she bubbles over with excitement about those few weeks this past summer which were for her ‘a dream come true’.

The business aspect, she explains, was the first ‘wow!’ experience. “Everything happened really fast,” she remembers. Without having time to think it all over, she found herself thrown into the Hollywood business. Within minutes after talking to Questas, her phone began ringing nonstop. She received several calls from the film studio, and was sent a lot of paperwork to sign her up as the leading star’s dance coach for the production of Felt. Once that part of the deal was settled, it took just about another five minutes for Liam Neeson’s agent to call and schedule the lessons for his client. As she was about to give directions to her dance studio, the agent politely interrupted and explained that Mr Neeson was a very private person and that the lessons had to take place at his house.

Quickly rearranging her own schedule, she agreed and then ‘spent the rest of the day watching all of Liam Neeson’s movies to see how he moves’. The very next day at eleven in the morning, she found herself sitting in this ‘very big apartment’ where everybody was ‘so very nice’ to her, waiting for her famous student to arrive, a cup of tea in front of her.

“At that moment it hit me,” she tells me with her delightful accent. “I was going to teach Liam Neeson! Oh my God!” But there was no time to be nervous. She heard him approaching through the living room, and listened intently to the sound of his shoes as he moved across the floor. “I hear how strongly he walks,” she remembers, audibly smiling over the phone, “and what a connection his feet have to the floor!” As she quickly took a mental note of his characteristic steps, the door opened and the star himself appeared and greeted her.

Despite his imposing size – he is said to be six foot four — Liam Neeson turned out to be shy indeed. He thanked her politely for coming to his house and introduced himself humbly: “Sorry, it’s going to be very hard!” Just as Questas had indicated, he had no dance experience.

So Karina started with some basic walking exercises. After the first round of walking with her new student she could feel how her own nervousness fell away. She says she settled into her role as the teacher and ‘stopped thinking about how famous he was’. Her new student on the other hand turned out to be ‘very respectful to learn’. And indeed he had a lot to learn. Not only did he have to master the basics in tango, but he also had to memorize Marcos Questas’ choreography to the piece he had chosen for the movie: Osvaldo Fresedos’ Vida Mia. “Simple,” states Karina, “but difficult for a beginner.”

Another challenge in teaching him was that the actor, whom she came to realize was a sensitive person, was initially afraid to dance. So she decided to take it slowly — “I did not want him to be in shock!” — and not think about the time pressure — she had to get her famous student ready in only fifteen hours over the stretch of three weeks.

“You need to practice!” she told him decidedly at the end of the first lesson. “We meet again tomorrow!” She also suggested that he wear dress pants and a shirt to get a better feeling for the elegant movement of the dance.

By her return the following day, Mr Neeson had done his homework and practiced a lot. And he continued to be prepared for all the lessons that were to come. “He really wanted to learn,” she explains, impressed by how seriously he took his tango studies. “He was a very smart student and he really wanted to understand.” His sincere interest in learning and his disciplined way of studying were well received by his Argentine teacher. They developed an artistic connection that Karina describes as very special. “This connection on an artistic and human level was the biggest gift for me,” she says.

But she still had to push for fast progress. At some point she provoked the actor in him, inviting him to find his role in tango and act it out on the dance floor: “If you were a singer,” she said, “you’d be Julio Sosa. This is the voice you would be in tango.” That was the magic trick. She had him practice to some Sosa tunes and says she could see how he changed and started to connect more.

The big breakthrough, however, came when she introduced Mr Neeson to Gabriel Missé, one of the hottest stars of recent years in the world of Argentine tango. Mr Missé happened to be in town for a workshop series that Karina arranges every year in August. She told Mr Neeson about Missé, and he became interested and asked her to bring him along. It was obvious that both men, each one a star in his respective artistic field, clicked immediately.

Mr Neeson asked Karina to dance with Missé — a moment which she describes as ‘being in heaven’ — and noticed how he enjoyed watching their little demonstration. Next, the two men danced together. She put a tango hat on Neeson and said: “Now act!” And then in front of her eyes something magical developed: As Liam Neeson danced with Gabriel Missé, he became Julio Sosa, executing all the steps he had learned: the ‘baldosa’, the ‘cunita’, the ‘box’, and the ‘sandwichito’. “It was a dream come true!” she revels. “And I saw two big persons together!”

When their coaching sessions came to an end and Mr Neeson started to prepare for the shooting of the film in Atlanta, he thanked her profoundly, promising to make her proud. She in return threatened jokingly: “I will kill you, Liam Neeson, if you don’t dance well in the film!” She remembers being quite nervous the day when the scene was shot far away in Atlanta. Finally she received a message saying: ‘Thank you, maestra, you helped me a lot!’

Mark Felt is going to come to theaters next Thursday, September 29, and I wonder if her name is going to be in the credits? “I don’t know,” she replies. “I’m relaxed about this. I believe this experience was a gift of God. There was an artistic connection, a magic, and the magic happened in the human part, in the connection of the soul.”

Did she get invited for the opening night? No, she says, but for sure she is going to be among the first ones to watch it — with a group of her girlfriends, somewhere in New York.
