8. Babel

(Alejandro González Iñárritu, 2006)

Multi-stranded high-drama/tragedy straddling Morocco, Mexico and Japan.

Danger, danger! A scene of strobe-lit nightclubbing was at the centre of a public health warning in 2006, after several people reported experiencing nausea and headaches during the sequence.

Oddly, only Japanese cinemagoers were affected, recalling a similar incident in 1997 when around 700 children had seizures during flashing-light sequences in a Pokémon episode.

Perfectly illustrating the media's penchant for alarmism, a Japanese news clip upped the 700 to nearer 12,000.

7. An Inconvenient Truth

(Davis Guggenheim, 2006)

Al Gore is your unlikely host for this impassioned essay on the stark realities of climate change.

Danger, danger! “Global warming has been stopped, gasoline costs 19 cents a gallon, George W Bush is Baseball Commissioner…”

The world as it could have been if Al Gore had won the 2000 Presidential race, according to Gore himself during his appearance on Futurama.

Having missed his shot at the White House, the environmental campaigner instead set about saving Earth with this impassioned plea for change.

It has influenced governments across the world, while a copy has been sent to every secondary school in the UK.

6. Man From Deep River

(Umberto Lenzi, 1972)

A British photographer is captured by a Burmese tribe and goes native.

Danger, danger! This grisly exploitation landmark kickstarted the cycle of cannibal movies which came out of Italy during the '70s and '80s.

Featuring genre-staple scenes of bloody violence, the film has the distinction of being banned twice in the UK under different names – on its initial release and on video as Deep River Savages.

It's also one of the movies that kicked off the '80s 'Video Nasties' panic.

Even today, four minutes of "unsimulated animal killings" remain cut from the DVD.
