Piotr Aleksander Adamczyk (Polish: [ˈpjɔtraˈdamt͡ʂɨk]; born March 21, 1972) is a Polish film, television, voice, and theatre actor. He is known for portraying pianist and composer Frédéric Chopin in the biographical film Chopin: Desire for Love (2002), Pope John Paul II in the TV miniseries Karol: A Man Who Became Pope (2005) and its sequel Karol: The Pope, The Man (2006), Tomas in the Marvel Cinematic Universe Disney+ series Hawkeye (2021), and Sergei Nikulov in the Apple TV+ original science fiction space drama series For All Mankind (2021–2024).

From his early childhood, Adamczyk wanted to become an actor. He attended the Machulski youth theatre group in Warsaw. Thanks to an international scholarship, he was able to attend international theatre workshops in the United Kingdom and Germany. He continued his acting education by attending the Theatre Academy in Warsaw. During his second academic year, he won a scholarship from the Soros Foundation, which allowed him to attend the British American Drama Academy for one year, where he performed Hamlet for his diploma. Once he graduated from the Theatre Academy, Adamczyk was hired by the Teatr Współczesny in Warsaw. His career in the film industry, however, grew much more intensively. He played Stawrogin in Fyodor Dostoyevsky’s The Possessed. The breakthrough in his career was his part as Frédéric Chopin in the film Chopin: Desire for Love—and he became a Polish star. The climax of his popularity was reached when he played the title role of another Polish historical figure in a two-part Italian TV movie—Karol: A Man Who Became Pope and Karol: The Pope, The Man. The movie was viewed by several dozen million viewers and made him popular in Italy, Latin America, and many other Catholic countries. Adamczyk also managed to take advantage of his popularity abroad to act at the Sala Uno Theatre in Rome, in Italian. He also appeared in Liliana Cavani’s movie Einstein and in the Portuguese production Second Life. In 2014, Adamczyk, Bartosz Opania, and Paweł Domagała starred in the comedy film Wkręceni. He has been in over 800 radio roles and around 100 theatre, television, and film parts. He is also appreciated for his roles in Polish dubbing. In animated films he voiced, among others, Melman the giraffe in Madagascar, Lightning McQueen in Cars, and Syndrome in The Incredibles. He has received many prestigious awards in Poland. In 2011, he was voted the most popular Polish actor. Description above from the Wikipedia article Piotr Adamczyk, licensed under CC-BY-SA, full list of contributors on Wikipedia.
