Spider-Man villain James Franco has laughed off reports his love scene with Camille co-star Sienna Miller was a dream come true, insisting the British beauty's toothache made filming it a nightmare.

Franco admits filming the scene was far from enjoyable and had to be cut short when his co-star complained.

He says, "I think we kissed once in that film and it wasn't at all intense - there was no rolling around or anything. Sienna's molar was giving her pain so she called the dentist!"
