I got up before 5am so I could be at the MCA to watch dawn break on Christian Marclay’s 24 hour video artwork, and it was kind of a letdown – a pink smudge on a dirty Paris skyline – in the way dawn often is. The idea: a 24 hour supercut of movie clocks that tells the time minute by minute is simple. But the execution is breathtaking. My favourite moment? Bill Murray’s Groundhog Day 6:00am wake up.
