The Ghost Scene

In Zeffirelli's version, the characters emotions were portrayed immensely. The setting was very dark and mysterious, contributing to the scene with a super-natural sensation. Hamlet (Gibson) and the ghost were both in spitting distance of each other, further contributing to the emotional dismay. The ghost was rather hurt and sad more than angry. Gibson finds rage when he looks at Claudius below him and begins writing on the rocks with his sword. This version is the most emotional and empathetic of them all. 
In Branagh's version, the characters were portrayed differently. The ghosts tone  and visual preference was very eerie and unpleasant, adding to a more creepy and rueful setting. The director also enhanced the plot by having the camera focus on different things (ex. close up on the ghosts mouth when he was talking revenge) like showing the present and past moments during the ghost's discussion. Some props that were used were colored contacts that was worn on the ghost, blood, etc. I appreciate the way the director, Branagh, focuses on many different perspectives and his ways to achieve them. 
In Almereyda's version the setting was more modern and contemporary. The ghost was very human-like, including the mannerism, even the way he had a coat draped around his arm, makes the scene a lot different from the previous versions. In this version, Hawke and the ghost actually share physical contact (spirit running hands through Hamlet's hair, and the two hugging) which contributes to a threatening kind of feel. Hawke's reaction was a lot more frightened and blasphemous in this version too. 
If I were to interpret this scene, I would use some techniques from every one of these directors. I would show different transpiring events during the ghosts monologue, like Branagh. I would have the more super-natural feeling to contribute to the ghost scene, like Zeffirelli. In this scene the most important part is the emotions, the rage, and the expressions. Through directional choices, one could probably argue that Hamlet made the entire thing up, however in Almereyda's version with the physical contact, that it make it a little more difficult. 
Though these three versions were contrasting, all displayed absolute and admirable strategies for recreating the scene.
