Sam wore a Sarah Burton for Alexander McQueen bridal gown, while Aaron suited up in bespoke Tom Ford. The couple, who met on the set of the 2009 film Nowhere Boy, are parents to daughters Wylda Rae, 23 months, and Romy Hero, 5 months.
This is the bride's third trip down the aisle. The Love You More director also has two daughters from her previous marriage to art dealer Jay Jopling: Angelica (born in 1997) and Jessie (born in 2006).
Aaron's other acting credits include The Illusionist, Kick-Ass and Albert Nobbs.
