went and saw a screening of this movie. Excellent acting. That tickling scene they show a bit of in the trailers goes on for a tad bit longer but afterwards..for you belly button lovers...Natalie Portman lays there with her belly exposed and starts picking and fingering her navel for what seems to be 5 mins or so while talking with Jude Law. Nice scene. After that, he gets on top of Natalie while she lay in bed with her arms are over her head, kissing and talking. In this lil scene, Jude laws hands skim up to her armpits and you can clearly see a ticklish reaction as she jerks her arm down with a big smile and silent laugh.
