20 Things You Didn’t Know About Trainspotting

20. Ewan McGregor And Johnny Lee Miller Turned Up Drunk For That Park Scene

As you'll likely discover a few more times over the course of this list, the overall atmosphere when it came to the on (and off) set world being shepherded by the legendary Danny Boyle can best be described as "relaxed". Or in other words, everyone involved seemed to be having the time of their bloody lives.

But in the case of Ewan McGregor and Johnny Lee Millar in the lead-up to the now-classic scene depicting their characters firing an air rifle at a dog in the park, that laid back mentality opened the door for one particularly p*ssed up performance.

Rocking up to set still drunk after a heavy night of antics, the two were forced to lie down for the sequence as they were struggling to actually stay on their wobbly feet. But, turning Guinness into gold, Boyle was able to channel their genuine states into a seemingly hungover bout of target practise.
