Plot hole: Just how exactly did the bomber get all of those drums on the ship unnoticed? Then, why didn't anyone question the appearance of the drums that are in very conspicuous locations?
Juggernaut (1974)
1 plot hole - chronological order
Directed by: Richard Lester
Starring: Anthony Hopkins, Richard Harris, Omar Sharif, David Hemmings
Other mistake: When Sir Anthony Hopkins (playing Johnny McLeod) is awaiting the arrival of the suspected bomber O'Neill (played by Cyril Cusack), a funny mistake occurs. Cusack sees Hopkins, smiles and greets him with a cheerful "Hello, Tony!" instead of "Hello, Johnny!" Being a pro, Hopkins doesn't blink an eye!
Lt. Cmdr. Anthony Fallon: I blew a great big hole in your ship, Captain. I'd better give it back to you.
Trivia: The MacGyver episode "Countdown" was a remake of this film. Initially the bomb defusing scene is replicated in part in the Kurt Russell film "Executive Decision"
