[2] In 2008, while still attending classes in the 10th grade at the Jakob Westholm Gymnasium, Müürisepp was approached to appear in the starring role of Tom in the Hannu Salonen directed crime-drama feature film Vasha, about a naïve sixteen-year-old schoolboy who finds himself to be an unwitting accomplice in a deadly game of vengeance after befriending Artur (played by Mehmet Kurtuluş), a Chechen man who is eager to avenge the murder of his family.
After filming was completed, Müürisepp returned to Jakob Westholm Gymnasium to finish his secondary education as well as studying acting and puppetry from 2009 until 2011 at the Estonian Puppet and Youth Theatre (NUKU) in Tallinn.
Some of his most memorable roles since joining the NUKU include those in stage productions by such varied international playwrights and authors as: Victor Hugo, Franz Kafka, Astrid Lindgren, Mati Unt, and Oscar Wilde, among others.
Müürisepp's impersonations included Antonio Banderas, Nancy Sinatra, Rolf Roosalu, Shaggy, James Hetfield of Metallica, Tina Turner, and Jaak Joala, among others.
Klassikokkutulek follows three middle-aged men (played by Mait Malmsten, G-Enka aka Henry Kõrvits, and Ago Anderson) who decide to attend their twenty-fifth high school reunion.
