There's a piquant French perfume to our April round-up. DVD of the month is Olivier Assayas's magnificent family drama Summer Hours, reissued in the US with revealing extras (and available worldwide from Amazon). Maurice Pialat's work is considered at length and Séraphine and Rumba are among the new releases. We unearth an extraordinary Czech epic,The Valley of the Bees, and watch Ernst Lubitsch's delicious early Berlin comedies. Films covered previously, including New Moon, The White Ribbon, 2012 and Zombieland are noted in brief, with a link to the original review. Our critics are Anne Billson, Tom Birchenough, Alexandra Coghlan, Graham Fuller, Fisun Güner, Sheila Johnston, Veronica Lee, Jasper Rees and Adam Sweeting.
