Jack Reynor, the star of the acclaimed What Richard Did, is to make his US movie debut opposite Vince Vaughn in the Steven Spielberg production The Delivery Man.

IFTN reports that the Wicklow actor was cast in the movie after Spielberg saw his audition tapes.

The Ken Scott-directed film, which also stars Dublin actor Simon Delaney, is currently shooting in New York and tells the story of a sperm donor (Vaughn) who discovers he is the biological father of 533 children, many of whom want to meet him.

Reynor will play a young American named Josh, while Delaney will play Vaughn's character's brother.
