Plot hole: At the end of the film Mardukas reveals that he has been wearing a body belt packed with cash - "in the neighbourhood of three hundred thousand dollars" - ever since Jack detained him in New York. Are we to assume that Jack Walsh, an experienced, hard-bitten ex-police officer, now a bounty hunter who routinely chases down violent and armed bail absconders who would kill him without a second thought, didn't even perform a perfunctory search of Mardukas when he detained him? This man used to work for the Mafia! What if he was carrying a weapon? A body belt with three hundred one thousand dollar bills in it would be uncovered by even the most casual pat down.
Midnight Run (1988)
Starring: Robert De Niro, Charles Grodin, Dennis Farina, Yaphet Kotto, Martin Brest
Continuity mistake: When Jack and the Duke are in the restaurant car of the first train, Jack is eating a chicken leg in one shot. In the middle of a sentence he changes to eating jelly and ice cream, which he finishes. In the very next shot his bowl is full of jelly and ice cream again.
Continuity mistake: At the beginning of the movie when Tony and Joey (Morons #1 and 2) meet Jack Walsh at the car rental desk, Tony writes a phone number on a packet of matches in pencil. Near the end of the movie when Jack Walsh fishes this pack of matches from his pocket, the phone number is written in pen.
Trivia: All of Dennis Farina's scenes were shot in Las Vegas; he was there filming his TV series Crime Story at the same time.
Jack Walsh: Here come two words for you: shut the fuck up.
Jimmy Serrano: Don't say a fucking word to me, Sidney. Don't you say a fucking word, or I will get up and bury this telephone in your head.
Jimmy Serrano: Is this moron #1? Put moron #2 on the phone.
Suggested correction: He was using $1000 bills. That's 300 bills in the belt which spread evenly absolutely could have been missed near his waist as part of his clothing.
Rubbish. I specified $1,000 bills as that would be the smallest package he could have secreted about his person, and it would still be instantly detectable. If he used $100 bills the package would be ten times larger, and he would have to carry a rucksack under his shirt.
