Katharine Hepburn is pretty ugly in this movie

Get your eyes checked! She's fabulous!

Maybe not pretty, but beautiful in a striking and mature way. And beautiful > pretty.

I liked it when she and Rossano Brazzi did the Lady and the Tramp noodle thing, but with a sausage, in Summertime (1955)

There's like a freaking 100 titles for "Summertime" on IMDB.

how old are you?

She was 44 and past her prime, but I wouldn't say she was ugly. And they didn't try to make her look glamorous in the movie, they actually tried to make her look like you would expect a missionary to look at that time which would have been plain at best.

Oh, be nice.

No, I'd say she was ugly ugly.
