Another one of those 'Oh shit, I've realised I'm in love with my bestie before they get hitched' movies. What? That's a genre... practically. It does star McDreamy himself though Patrick Dempsey, alongside True Detective's Michelle Monaghan, and his former Grey's Anatomy co-star Kevin McKidd even plays his love rival. Michelle arrives back from a business trip in Scotland all mad about Kevin. McDreamy is her Maid of Honour, but it looks like he may try steal the bride, so is he really made of honour... huh? See what they did there? Ah you do.
