Director and writer Joshua Stephen Buckner is LT Sean Snyder's brother-in-law.
Sean and Amy Snyder were married at ages 16 and 18. Because Amy was a minor the couple had to get married in Lake Tahoe Navada because you can get married in Navada at 16. Amy just needed her mothers signature.
The title "Five Days in Winter" was chosen because this was the amount of days the Navy and Coast Guard searched for Lt. Snyder before he was found.
