Okay, I've had a think - and here goes - I apologise if there is a similarity to Greg's post - but I honestly came up with these before reading his post! This list is more about those characters that have been influential as opposed to just fun and popular (although most of these are fun and popular!)
1. Mickey - I have similar feelings to Greg regarding this character. However he is the dominant icon of animation - his silhouette is known world wide. You just need to see the 'three circle design' anywhere and you immediately think of Disney. He is just way too valuable and influential to ignore - he is my number one.
2. Seven Dwarfs - again, these are icons of the Disney brand - instantly recognisible symbols of animation quality, family entertainment, and the Disney company. They have appeared in every Disney Parade I've seen (except the Block Party Bash at DCA).
3. Ariel. Huh? I hear you say! Well let me explain - she is the first of the new generation of Disney female stars - headstrong and sexy - a far cry from the earlier portrayal of women in Disney films (meek, mild, and requiring men to save them, like Snow White and Sleeping Beauty...) Her movie began the Disney animation revival in 1989 - for which I am eternally grateful. Belle is still my favourite female character (she is the reason I returned to watching Disney movies after a 15 year hiatus) but Ariel started the new Disney.
4. Donald Duck - he is the perfect counterpoint to Mickey's perfect lifestyle. Mickey wasn't always perfect - in fact, he was downright cruel in the early days. But as his fame grew and he became that Disney symbol (see item 1.) he had to stop being a bad boy and support the company banner. Donald was the perfect solution to that - he can be as cranky as he likes - he has attitude and personality in spades (something Mickey sadly lacks), he has a great heart and he is extremely funny. If he is a bad boy - he doesn't affect the company stock price!
5. Buzz Lightyear - this is a questionable one for me - I feel I have to add someone from the Pixar fold, because these movies have changed animation forever (and not just from Disney). Without doubt Toy Story is Woody's movie, however he is just too clean cut to make this list - a bit like Mickey Mouse, but Woody doesn't have the Mickey Mouse symbology that got Mickey into the number 1 spot. So I've chosen Buzz - he is not perfect, but he is a modern symbol of the new way of movie making. I saw more kids that were excited to meet Buzz than Woody in Disneyland last year, and just like in the Toy Story movies, Woody is a bit old fashioned and has that pull string voice box - Buzz is plastic and has a red light he thinks is a laser, and three different voice recordings on his buttons! He is the winner here
Now, if my girlfriend was writing this list for me, she would say my favourite five are:
Belle, Ariel, Cinderella, Sleeping Beauty, Snow White. As she pointedly stated to a cast member in Hong Kong last month while I was getting Cinderella's autograph "Keep taking photos - he likes the Princesses!"
