While studying business management in college, Radan signed up for acting classes where he was discovered as an emerging talent. He got his first break when he was given an opportunity for his first role starring in the movie The Passion of Love. The movie achieved great success at the Iranian box office and was one of the top-grossing movies of 2000. Radan has since starred in many movies and has become a popular household name in the Middle East, often referred to as one of the top five superstars of Iranian cinema. His extreme popularity caused Iranian authorities to ban his images from billboards in 2008. In 2010, he was chosen by United Nations as the first Iranian UN ambassador against hunger.

He ventured into music and released his first album, The Other Side, in 2012. Music videos were created for three of the songs from the album: “Jeegh” (Scream), “To Rafti” (You Left) and “Zamouneh” (Era).
