Where did John Ryan pick up the nickname "Jack"?
The protagonist in the Jack Ryan films is actually named JOHN Ryan. I'm not too familiar with the book version of the character, as I've only read a couple of the books. The movies don't mention where the name "Jack" comes from, but uses "Jack" as of his first appearance in "The Hunt for Red October", and even in "The Sum of All Fears", which is chronologically set much earlier. I'm hoping a fan of the series can shed some light on the origin of that nickname.
Do any of the films containing Jack Ryan mention where he picked up the nickname "Jack"?
Best Answer
Jack is simply a common nickname for John -- the most famous example being President Kennedy, who was called Jack from birth by friends and family. Ryan is Irish Catholic, as seen in the Patriot Games movie and various elements of his biography in the books. We can presume that his parents wanted to call him Jack but, being Catholic, baptized him with the name of a saint.
