Nostalgia for Trainspotting is at a recordhigh this week with the release of recent visitor Danny Boyle's long-awaited and debated follow-up T2: Trainspotting.
Although the original film contains plenty of iconic moments, none has lingered more vividly in all of our minds as the bit where Renton (Ewan McGregor) climbs into a particularly filthy porcelain throne - all too accurately keyed on screen as 'The Worst Toilet In Scotland' - in order to retrieve a mistakenly deposited suppository.
Although Boyle portrays Renton's metaphorical time 'inside' the loo as a occurring within a relatively clean-looking pool of water, the suggestion of what is happening is more than enough to make the scene grossly traumatic. As is the toilet's rim, and surrounding cubicle.
To celebrate this disgusting milestone in cinema, I will cite here five other iconically icky, must-turn-away, squirm-inducing moments from contemporary cinema.
