Ben Affleck premiered his Argo at the BFI London Film Festival this evening. He was joined at the Odeon Leicester Square theater by his leading men Bryan Cranston and John Goodman. Ben brought the thriller, which came in at the No. 2 spot at the US box office last weekend, to England after a stay in France with his wife, Jennifer Garner. Ben and Jen's romantic trip to Paris lasted only a few days, but they were able to fit in a shopping excursion to Chanel and even a romantic dinner date. The London Film Festival has also brought Marion Cotillard to England — Marion debuted Rust and Bone there over the weekend.
