The moviemaker agreed to screen test the relative newcomer after spotting him in acclaimed movie What Richard Did.
According to The Hollywood Reporter, the young actor was one of five stars who auditioned to play the love interest of Wahlberg's movie daughter in the latest Transformers film.
Reynor was reportedly up against Taken 2 star Luke Grimes and TV actor Hunter Parrish, among others.
And he has already found a fan in Bay after taking a big chance at breaking into Hollywood last year (12).
The director states, "He is an Irish kid that came to America with 30 bucks in his pocket. Pretty ballsy. Seriously, who does that...? I spotted him in a great little Irish movie What Richard Did. This kid is the real deal."
