The world is turned literally upside down in Revanche's long, eerie opening shot. We see trees reflected in a dark forest lake, hear animal and bird sounds - discordant, wild, somehow unsettling - and the faint boom of distant thunder. Then something (we can't see what) plummets into the water. This superlative psychodrama sends out ripples too, that last way beyond the tight parameters of its plot.

Danish director Nicholas Winding Refn has already displayed unsettling form as a filmmaker intimately acquainted with violence. His Pusher trilogy probed into the black heart of Denmark's criminal underworld, while Bronson surfed a monster wave of ultraviolence in its account of psychotic jailbird Charlie Bronson. With Valhalla Rising, Refn has thrown his gears into reverse and screeched backwards to Pagan-era Scotland, though the director may be intending his location to evoke an all-purpose Nordic wilderness.

One evening in 1970, Princess Anne ventured forth from her manor to attend a screening of Bronco Bullfrog at the Mile End ABC. Three decades later, the same cinema, now called the Genesis, hosted a screening of Barney Platts-Mills' debut feature last night in equally ceremonious circumstances: the launch of the East End Film Festival. Rarely seen, indeed almost lost (the original 35-mm negative was salvaged from a rubbish bin at the film lab), Bronco Bullfrog, which will be released nationally on 11 June, emerges as a minor revelation.

A father keeps his three adult children in a state of retarded development. They are deprived of books, education, television, indeed denied any access to the world beyond the electronic gates marking the perimeter edge of their known territory. In the place of knowledge is disinformation, disseminated on tapes. The sea is a leather chair, a zombie is a yellow flower, a vagina is a keyboard. And so on. In all this the mother is quiescent, complicit. The father is an absolute patriarch, the source of all morality and law.

Many is the mother the world over who announces that she won't die happy until she has lived to see her daughter (or son) happily wed. And so, out of a familial condition that transcends ethnicity and geography comes It's a Wonderful Afterlife, the Gurinder Chadha movie that carries this shared fretfulness one step further, throwing in curry jokes as it goes.

Amazing untold stories remain waiting for cinema. Alejandro Amenábar has found one in the female philosopher Hypatia's quest for knowledge during the religious turmoil that gripped 4th-century Alexandria as the Roman Empire fell into the Dark Ages. Somehow he has managed to parlay the freedom given by his 2004 Foreign Language Oscar for The Sea Inside into a cosmic, 50-million-Euro epic of ideas which leaves Hollywood's narrow narrative parameters far behind.

BD, pronounced bédé, is short for "bande déssinée", the French equivalent of the comic-strip or graphic novel, which has long been accorded a popular affection and cultural standing well beyond that of its anglophone equivalent. Luc Besson says he was weaned on BD, which comes as no surprise to anyone familiar with his films. The only surprise is that it has taken him so long to direct an adaptation of one.

Cemetery Junction is no ordinary day in the office for Ricky Gervais and Stephen Merchant. Anyone seeing their names above the title (or, indeed, Gervais’s inappropriate presence on the poster) could be forgiven for expecting their acute observational comedy, fronted by Gervais’s shtick for wince-inducing egomania. Think again.
