I'm not saying that there should be a remake, but it's fun to fantasize about one.
Right when I saw James Booth, I thought a cool remake would be with Jemaine Clement in the role of Tuttle.
Does anyone have any thoughts on the other characters? Maybe Emma Stone or Rachel McAdams as Mrs. Blossom?
Maybe an old thread, but interesting idea. I think this movie worked magnificently BECAUSE of the 60s film-making qualities it had. The narration and odd style wouldn't translate as a modern film, so you'd need a director with a different kind of edge who could somehow still bring the same quirkiness, but in a fresh (un-pretentious) way.
Not sure about casting. Definitely think you're right about Jemaine, but I absolutely adore him. only actor I can immediately see myself being charmed by, given the fact that he's a live-in lover.
Rachel McAdams is also another nice choice. She's got just enough beauty and depth for it, without being too innocent.
If he was just a little younger, I could see William H. Macey playing Mr. Blossom. Given that he is, alas, maybe a decade too old now, perhaps Ewan Mcgregor or Edward Norton?
