Katharine Hepburn movies

This has a very Shakespeare- like feeling about it, but is based on a play by J. Goldman.
The plot is a bit complicated, but there are some facts:
-the story is inspired by real events, occurred during Henry II reign, when England was in full centralize process.
-the action is set in Chinon, during Christmas, the year -1183.
Before becoming king, Henry married Eleanor of Aquitaine, after her divorce from the king of France, so he gained a wife and a huge territory on the side.
When the marriage became a mess, Eleanor encouraged her sons to rebel against the king. The queen was put under house arrest, as a punishment, but freed "on special occasions", like Christmas.
So, how would a Christmas in the Plantagenet family look like? well, like a war at home...
Even if the story is interesting, the strengh of the movie comes from the complex characters ( a bit to complex for my taste) and the strong performances by a really inspired cast.
Hepburn is mesmerising as Eleanor. Was there ever e better actress? O'Tool is equally good, as well as the very young Anthony Hopkins (Richard), Nigel Terry as John, T. Dalton as king Philip, but my favorite from the supporting cast was Iago like Geoffrey ( John Castle).
On the negative side, although I'm a lover of dialogue driven movies, at times this was too much even for me.
And all the characters were struck by bipolar disorder?
A last thought, I saw the 2003 tv version, with Close and Stewart, I find it pretty close, actually.

Based on a play by Tennessee Williams, "Suddenly, Last Summer " is about Catharine Holly, that descend into madness after her cousin is murdered.
Seems that while they were in Europe, something horrible happened that triggered this unfortunate event. The thing is, she not really insane, but her aunt, a very influential woman, tries to convinces doctors that Catharine needs a lobotomy, beeing despaired that anyone would found out about her late sons homosexuality.
The rest of the movies revolves around Catharine and her tryings in convincing anyone that shes not demented.
Well, I didn't buy it, I think would've been way easier for Violet Venable (Hepburn) to buy Hooly's silence, and send her away, why go all that trouble and buy everyone else around her?
And, as usual, Elizabeth Taylor is overracting, while Montgomery Clift is stiff and not showing that much. Hepburn is good, but she always is.
The interesting fact is that Williams' sister Rose was compelled to undergo a lobotomy at the instigation of their domineering mother.
