Here, we give you five things you must know about Reynor.

1. Homeland: He may have been born in Colorado, but Reynor has a thick Irish accent. He and his human rights lawyer mom Tara O'Grady moved back to her native Ireland when he was just two years old.

2. Hollywood or Bust: After he did some acting in Ireland, Reynor decided to move to Hollywood in 2012 after getting good reviews at the Toronto Film Festival for his work in the indie What Richard Did. He only had $40 to his name at the time, but three months later he was cast in Transformers.
