I read the reviews for this film before I tried watching and I found my reaction was somewhere in the middle. Some described it as being among Jerry Lewis' worst films, though I think films like "Which Way to the Front?", "Cracking Up", "Slapstick of Another Kind" and "Three on a Couch" are much, much worse. And, it certainly is no work of great genius like some have said. It's a decent little time-passer with a few faults.

When the film begins, Jerry is fishing and somehow hooks onto someone in a wetsuit. The guy ends up being a gangster who could be Jerry's double and he tells Jerry about some hidden loot. As for Jerry, he wants to do the right thing and tries to get police and others to listen to his account of catching the man...but no one seems willing to listen. And, as for the gangsters who shot the man Jerry caught, they are now looking for the fisherman because they think the dead man must have told him about the money. Despite this being the theme, the movie is almost plot less at times, a bit like "The Bellboy"...which isn't all bad since this earlier Lewis film is among his best. Now I am not saying all the silliness or Jerry's dressing up like the Nutty Professor work most of the time...but it is pleasant and diverting during much of the film. Overall, no bomb nor work of genius but a generally decent little film that will offer a few laughs...just a few. There certainly could have been more laughs and Charlie Callas was simply awful...but fortunately he was only used sparingly in the picture. Also awful was Lewis' embarrassingly bad imitation of Japanese folks...a definite low- point in the film...or in any film that came out that year.

By the way, look quickly and you might spot Rob Reiner in his film debut. You'll also see Colonel Sanders...though he is pretty obvious!

This time, Jerry Lewis plays reporter Gerald Clamson, who just happens to be a dead ringer for Sid Valentine, wanted by a crime syndicate. The only thing is, Valentine is supposed to be dead, so when the thugs see Clamson, you can imagine what sorts of things they do! Mistaken identity seems to be a frequent source of comedy (or drama; see "North by Northwest"). So even though "The Big Mouth" is nothing special, it's good for a few laughs. Most of the laughs come from what happens with the thugs when they see Clamson. But one also gets the feeling that Lewis was sort of losing his ability to come up with anything new after this. And now that we know what sort of a person he is in real life, that weakens it. But overall, this one's pretty funny.

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 ****
