Jack Reynor is on the verge of transforming into something big.

The 22-year-old actor costars alongside Mark Wahlberg and fellow newcomer Nicola Peltz in Transformers: Age of Extinction, director Michael Bay's latest flick in his megahit action franchise (in theaters tomorrow, June 27).

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.
