I wish I could help it, but every time a woman (or a group of women) registers astonishment at something another woman has said by saying “oh…my…god!” I feel hugely repelled. In real life, in a TV series, in a film…anywhere. Chalk on a blackboard times ten. So I’m naturally concerned about a moment in the Mamma Mia trailer in which Amanda Seyfried tells her friends she has three possible dads coming to her wedding and she doesn’t know which is the actual sire, and…you know the rest. Where there’s smoke, there’s fire. Fingers crossed. It opens on 7.18.
