In the movie, Keira's Juliet is in a relationship with Chiwetel Ejiofor's Peter, but his best friend Mark is also in love with her. He shows up at their door and uses cue cards to communicate with her so that Peter won't hear him.
"The slightly stalkerish aspect of it -- I do remember that. My memory is of [director] Richard [Curtis], who is now a very dear friend, of me doing the scene, and him going, 'No, you're looking at [Lincoln] like he's creepy,' and I'm like [in a dramatic whisper], 'But it is quite creepy.' And then having to redo it to fix my face to make him seem not creepy," Keira told the Los Angeles Times.
Keira was asked if she felt a creep factor while filming the scene.
"I mean, there was a creep factor at the time, right? Also, I knew I was 17. It only seems like a few years ago that everybody else realized I was 17," she said.
