was trying hold my laughter in during first emperor scene
after he sends mace windu out the window. i held it in. i'm not usually even a laugher. when he names anakin lord vader and says gooood. i couldn't believe everyone in the packed theater was just silent during that scene.
i don't think it's a sign of the performance being bad because i always found some of his line delivery in rotj to be funny and imitable, like when he sais he's afraid the death star is fully operational.
