I took a quick look at the issue with the messed up movie pages in Chrome because the lack of a fix was really bugging me, and I think I might have found the issue.
For some reason, the td and th elements for the movie title, the bunch o' links section, and the category section all have:
style="height:1%"
in the tag. If you remove that height style (I did so with Chrome's element inspector), any messed up movies get fixed.
I'm guessing that for some reason, this 1% height overrides the CSS and/or automatic height calculation sometimes, but not always. It isn't really clear why that happens, but I guess something in Chrome changed at some version and that local style sometimes broke it.
So perhaps if you remove the 1% height thing, this will be fixed. I don't really have the time to test whether or not this breaks something in another browser though... I have a feeling it might be there for a reason (old version of IE, maybe?).
