John Heffernan is a British actor. He has worked with the the Royal Shakespeare Company (RSC), the National Theatre, and the English Touring Theatre. He has appeared in films and television shows.
The MCU as we know it but the first Iron Man was released in 1998 and Endgame was released in 2009. Cast actors who would have been age appropriate as well as bankable at the time. Do not cast actors who were in the franchise!
