GusF In spite of the welcome return of Kenneth Williams, this is my least favourite film in the series so far. The only other member of the core "Carry On" team present is Charles Hawtrey but that would not be a problem if the script were better. There are some good laughs in the first 20 minutes but, after that, all it produced was an occasional smile. It's surprisingly boring. It doesn't really feel like a "Carry On" film. Bernard Cribbins, Juliet Mills and Cecil Parker were all good but even good actors trying their best can't save a comedy with a bad script. However, Donald Houston, who is good in other films, is horribly over the top and his scenes are fairly painful. On the bright side, this is the eighth film in the series and it's the first one that I didn't like. Every other film series that I have watched with eight or more films produced at least one dud before that!

bkoganbing The Carry On comedy team takes on all those sagas of the British Navy from the Napoleonic Era with Carry On Jack. The title comes from what they used to call British sailors, Jack Tars.Midshipman Albert Poopdecker played by Bernard Cribbins is little thrown out of sea school just to make room and given his first assignment on the HMS Venus a frigate ship of the line. But on his way there Cribbins is waylaid in a cat house where one of the girls played by Juliet Mills steals his uniform and credentials. To make matters worse a press gang comes along and takes Cribbins and Charles Hawtrey.The HMS Venus has a Regency fop for a captain in Kenneth Williams and a first officer in Donald Houston who'd like to take his place. And Juliet Mills on board playing a midshipman named Albert Poopdecker. Her breasts are just super spectacular man boobs if she'd let the crew see them and confirm their beliefs.In the end after surviving a mutiny, a capture by pirates and saving the United Kingdom from invasion, Hawtrey, Cribbins, Mills, and Williams, are national heroes.But it's how they do it that provides loads of laughs in this Carry On classic.

Leofwine_draca Although it's not up there with the best of the CARRY ON series, CARRY ON JACK proves to be as likable and inoffensive as the majority of the films. This one suffers from a lack of regulars (only Kenneth Williams, Charles Hawtrey & Jim Dale appear) but makes up for it with great authenticity in the costumes and early 19th century locales.Bernard Cribbins (CARRY ON SPYING) stars as a Midshipman who's accidentally pressganged into working aboard one of the British's fleets ships. The usual slapstick and shenanigans occur, with much of the humour arising from delicate Juliet Mills masquerading as a man. Cribbins plays it straighter than you might expect, and doesn't get many gags (saying that, the one involving his sword and a carriage wheel is a classic), although Williams has fun as the cowardly Captain Fearless and both Dale and Hawtrey are delightful.

Chris Mooney (dhsb58) Many would say if the Name "Carry On Jack" was mentioned, "I haven't seen that one" or "That was terrible wasn't it." To many Carry On Fans..the film is often very underrated.This is due to a very large lack of regulars within it.Sid James is not in it, nor is anyone common from the Hudis films such as Liz Fraser or Ted Ray.This was in fact the first film "written" by Talbot Rothwell (though Carry On Cabby was screened first but written second).The film i feel is a classic.The jokes come thick and fast.Many are quite visual! (wont spoil it for you!) Superb Performances from Charles Hawtrey, Jim dale (In the little part he plays) and Bernard Cribbens(in fact his first carry on outing!).8.7/10
