I liked The Sound of Music! By the time I was 10, I had seen the movie 5 times (remember...no home versions) and stage musical at the LA Music Center. But I had heard it wasn't well thought of in the industry and that Plummer wasn't fond of it.
It's like Alec Guiness ruing being remembered for Star Wars. Its not a bad thing, he did well in it, and made a ton of money. But he had acted in so many other films, where he really showed what he could do--yet he'll be rememebered as Obi wan. I've read he was not happy with that.
