If even agreeing on a shopping list can require mediation in many relationships, spare a thought for Nolan and his wife Emma Thomas whose shopping lists include items like 'Batpods' and 'collapsing dreamscapes' (and milk, presumably). The pair, fellow students at University College London, have spun their undergrad relationship into a successful marriage, four kids, a production company (Syncopy) and a multi-billion dollar filmmaking partnership that began with short film Doodlebug and will continue long past The Dark Knight Rises. The Nolans are the only family whose Christmas videos are shot in IMAX. We think.
