An absolutely classic comedy on every frontier, the chemistry between the three leads is perfect, with each actor pulling his own weight to deliver in this comedy gem that has often been hailed as one of the best British comedies of all time. The jokes are not only funny but charming too most of the time, and although the plot and characters are quite silly, they are all well written for their purpose. The film's technical side is quite impressive too, in particular considering its age, with some great cinematography, a perfectly creaky set design and effective dissolve editing. The special effects and stunt work is also worth marveling at, and the overall film is largely enjoyable. It is not deep, and it is rather silly, but if those qualities can be overlooked, a fun, funny and generally well made film awaits.
