I've only recently 'discovered' narcissistic behaviour and it's been a real eye-opener to me. Now there are some characters in books and films that really hit me as narcissistic.
I'll go first:
Muriel's Wedding: Muriel's awful awful father
Jonathan Strange and Mr Norrell: the Gentleman with the Thistledown Hair
(although Strange and Norrell have traits I suppose)
Any more?
