After appearing in a number of Romanian films, 2017 brought Secăreanu his first English-language role in Director Francis Lee’s God's Own Country. In the award-winning drama, he was seen as a Romanian migrant farm worker Gheorghe, who begins relationship with a sheep farmer (played by Josh O'Connor) on a farm in Yorkshire. Director Lee had insisted on the cast of a Romanian actor in the role of Gheorghe. After winning the role, two weeks working on a farm followed before filming. "The two-week rehearsals helped me build the figure because I had to work in the yard, I learned to work with cows and sheep, watch the birth of lambs, cut sheep hooves, make cheese ...," said Secăreanu. His performance in God's Own Country earned him a London agent, membership in the British Actor's Union" and a nomination for British Independent Film Awards.
