If you are a Jerry Lewis fan, you have probably heard that this film – made in the Golden Year of 1967 – is the biggest pile of poop he ever made (although we have yet to see his "The Day The Clown Cried" and it is unlikely we will – at least, while Jerry lives). And that would be a fair description of this turkey.However, it is still worth a look – for three reasons.First and most important, he re-creates his Nerd character (Professor Julius Kelp) from "The Nutty Professor" – imagine a DVD of deleted scenes from THAT – you would pay money to see those, would you not? This is the next best thing.Second comes an extended shot of the late Charlie Callas (no relation to Maria) doing his "manic twitch" routine – it is almost worth watching this abomination for that alone. This was Charlie's ONLY film appearance and came about after they met on the Merv Griffin Show and he impressed Jerry so much, the latter promised to use him in his next project. Sadly, it turned out to be THIS.Last is a bizarre, two-minute cameo from Harland Sanders – yes, the old cross-eyed "colonel" himself. Many people today are unaware that the character on the KFC logo was once actually a REAL PERSON and he makes a fleeting appearance in this dross.Why? Well, perhaps HE was a fan of Jerry Lewis' movies – although it is unfortunate that he chose THIS one to make his film debut in

Jerry Lewis directed, co-wrote, and stars in this half-wit gangster comedy about a bank auditor who takes a fishing holiday and gets mixed up with jewel thieves who are after buried diamonds; turns out he's also the dead ringer for an allegedly-deceased crime syndicate boss...though that's not the reason Jerry spends half the movie in disguise as his bespectacled "Nutty Professor" character. Sloppy, stupid, braying farce, the kind of star-vehicle which hopes to ring laughs out of every silly gesture or cross-eyed reaction. Lewis plays the kind of fisherman who can't even push a sailboat away from the dock without falling into the water. Frank DeVol as Bogart (our deadpan narrator) is an unusual touch, and Colonel Sanders has a funny (if pointless) cameo. Otherwise, this "Big Mouth" is just an empty hole. * from ****

Jerry Lewis is a transitionalist between Vaudevillian slapstick and today's one liner comedic actors. In the Big Mouth, Jerry executes his humor with finesse. Younger audiences perhaps wouldn't enjoy this movie due to its lack of explicit sex, strong language, and graphic violence. That is exactly what makes this movie attractive. It is a great break from the routine movie, a chance to giggle and laugh. It is a good story that could be remade today into a suspense or comedy. Jerry shows his ability to be a flexible actor. Susan Bay was likewise good for her first starring role.

Smugglers have a falling out, and one of them high-tails it with the loot. When the gang finds out that Jerry unknowingly received the stones, they pull out all stops to get at him. That should have been easy, but the fools are more inept than Jerry. Of course, along the way Jerry falls in love. An amusing film.
