Winner of the Oscar for Best Live Action Short in 2006, Martin McDonough's directorial debut is about as black as black comedy gets. After the death of his wife a man (Brendan Gleeson) shares a train journey with a young sociopath determined to provoke others on the train, including a couple who have lost their baby. It's difficult to say too much without giving away the 'plot' of this quirky film but it is amazing that McDonough is able to find humour in cot-death, suicide and exploding livestock.
And it is funny.
To then wrap things up with an oddly touching ending is quite an achievement.
