... at least it would be completely in line with other decisions by Christopher Tolkien to refuse that Gandalf's image gets used on a stamp (even more in a series of famous Wizards and Witches...).

CT is most admirable and respectable for what he's done for his father's legacy and for Tolkien scholarship, but he pushes the whole cerberus thing a wee bit too far at times. He sure seems to struggle a lot accepting the fact his father's work is gaining an independant life, that Gandalf and co. have joined the likes of Holmes and co.

To get back to the topic, personally I don't mind Gandalf's look in the movies at all (some of his very un-Gandalf like scenes yes, but not his looks), it's one of the things I thought Jackson really nailed well (actually... that's more Alan Lee, since the movie character is the living and costumed version of his paintings of Gandalf. Visually Jackson's Gandalf certainly is much, much better than the HP movies' Dumbledore that missed the dichotomy Rowling created between his wisdom/dignity as a character and his totally whimsical/hilarious and even clownesque appearance that touched on satire of the "proper" british establishment (well, if we overlook the Royals' occasional Dumbledoresque moments, anyway).
