The cast tries hard to make a go of this entry into the British Raj in India genre, a genre which is still far and away dominated by RKO's Gunga Din released in 1939. Mostly it's a futile effort. The film comes up short on many levels. The screenplay isn't in the same league as the RKO classic and Stewart Granger, Robert Newton and Cyril Cusack are a pale shadow of Cary Grant, Victor McLaglen and Douglas Fairbanks Jr. Granger forces the issue constantly, trying to ape Cary Grant's performance in Gunga Din and it comes off primarily grating though he does have a few amusing moments.
The humor between the three is passable enough but Newton and Cusack just don't offer much chemistry or star power, and the script rarely gives them anything to do but banter at Granger and each other and down pints. David Niven, wasted in the role of a superior officer, would have been way better served to have been cast as one of the threesome instead of Cusack. Walter Pigeon, too, gives one of his clunkiest performances as the Colonel, much consternated British bluster is attempted but fails to be very humorous or believable.
The best sequence in the film is the brawl in the tavern with the Scottish soldiers, which is very much reminiscent of Gunga Din's opening, and the battle at the end is well staged and action packed, it just takes about 70 mostly wasted minutes to get there.
Overall the picture is not unentertaining, it has its moments but it's barely half the adventure masterpiece Gunga Din is.
