Is this your favorite Elizabeth Taylor film?

By far.

It’s one of favourite films of all time.

I prefer Giant.

So far it is. I've only seen a handful of her films. I'd say one of the most well deserved Oscar wins I've seen, too.

"National Velvet"

No, but it is her best performance, the one time she stopped being beautiful and just acted!

I think my favorite film of hers is "The Mirror Crack'd", in which she's absolutely terrible... but provides camp value. A lot of her career was like that.
