i love the scene where john convinces a female fan that he's not john lennon.
(just copied this from wikiquote)
Millie: [Gobsmacked, apparently recognising him] Hello!
John: Hello.
Millie: Oh wait a minute, don't tell me who you are...
John: No I'm not...
Millie Oh, you are...
John: I'm not.
Millie: Oh you are, I know you are...
John:: I'm not, no.
Millie: You look just like him.
John: [Acting surprised] Do I? You're the first one that's said that, ever.
Millie: Yes you do, look.
[She points John to a mirror, points a light-fitting over him]
John: No, my eyes are lighter, the nose...
Millie: Oh yes your nose is very...
John: Is it?
Millie: I would have said so.
John: You know him better, though.
Millie: [Defensive] I do not. He's only a casual acquaintance.
John: That's what you say.
Millie: What have you heard?
John: [Leaning close, quietly] It's all over the place.
Millie: [Grinning shyly] Is it? Is it really?
John: But I wouldn't have it. I stuck up for you.
Millie: [Touched] I knew I could rely on you.
John: [Humble] Thanks.
[Millie puts on her glasses]
Millie: You know, you don't look like him at all.
[John pouts and walks up the stairs]
John: [Huffily] She looks more like him than I do.
