Thanks for the info' everyone, and I'm doubly grateful to wofahulicodoc , but in the film it was definitely pronounced like 'punt'. Bundt is not something I've seen here in the UK, but I'm sure, now that I've heard the explanations, that there must be specialist shops that sell it; you can get pretty well everything here in London if you know where to go. It's just been an experience missing from my life! Sounds highly calorific though, bad for my cholesterol level!
