Praise Marx and Pass the Ammunition is a 1968 British political comedy-drama film directed, written and produced by Maurice Hatton and starring John Thaw, Edina Ronay and Louis Mahoney.

The film attempts to examine the dilemma of the extreme Left in Britain today, committed as it is to proletarian revolution .... John Thaw as Dom gives a suitably dry performance.

At this level, however, the film is extremely muddled, largely because of the shortcomings of the script, which mixes commentary and dialogue in what appears to be too indiscriminate a fashion for any sustained argument to be deduced.

Although it is part agitprop, with lots of facts and figures on social deprivation, it is, as the title suggests, mostly satire and takes amusing swipes at a Swinging Sixties stereotype, the Marxist-Leninist revolutionary with noble ideals and feet of clay.

...In a way, this is [Hatton's] own attempt to import the bracing atmosphere of Paris '68, with his mixed method (fiction and documentary, revolutionary comedy and direct address on the need for social change) owing something to the work of Jean-Luc Godard.

More than a little muddled anyway when trying to be serious, it was always much better at digging satirically into areas of bad faith as its hero, a 30-year-old Marxist-Leninist of working class origins (sharply played by a pre-Sweeney Thaw), seduces a string of bourgeois beauties in the hope of also impregnating them with his revolutionary message.
