With the “D-Day 75th Anniversary” event hosted by A Walk in Their Boots taking place Saturday from 9 a.m. to 3 p.m. at Sycamore Shoals State Historic Park, I’ve been thinking about movies based on D-Day. Of course, today everyone thinks of “Saving Private Ryan.” But how many of you remember “The Longest Day?” The 1962 epic featured a stellar cast including John Wayne, Richard Burton, Henry Fonda, Robert Mitchum and Sean Connery — just before he appeared as James Bond for the first time. Both movies are action packed, with the battle scenes in “Saving Private Ryan” being far more realistic.
