Sorry about that,Miss Gamgee.
(The elevator, as it's going up, stops suddenly. Obi-Wan and Anakin look at each other in surprise.)
Obi-Wan: (to Anakin) "Did you press the stop button?"
Anakin: "No,did you?"
Obi-Wan: "No."
(Anakin looks up)
Anakin: "Well, there's more than one way out of here."
(Anakin cuts a hole in the roof of the elevator)
Obi-Wan: "We don't want to get out we want to get moving.(sighing).R2, activate elevator 31174. Come in R2." (Anakin jumps out onto the elevator, Obi-Wan sighs) "Always on the move."
(R2 backs away into a dark corner and puts the comlink in one of his compartments.)
Obi-Wan: (Muffled) "R2, can you hear me?"
(R2 trundles over to an elevator thing at a panel. Anakin is on top of the elevator.)
Obi-Wan: "Come in R2."
(R2 finally turns the elevator on: going down. Anakin jumps onto a ledge. Obi-Wan is thrown onto the floor.)
Obi-Wan: "Whoa, R2....."
Obi-Wan: "Stop, stop. R2, we need to be going up."
(R2 works on the elevator. He finally stops it. Obi-Wan is again thrown to the floor. He then turns it another way, getting it to go up.)
Obi-WAn: "Now, that's better."
(the elevator comes quickly at Anakin. He jumps off the ledge and into the hole of the elevator. Obi-Wan ignites his lightsaber.)
Obi-Wan: "Oh, it's you."
Anakin: "What was that all about?"
Obi-Wan: "Well, R2 has been..."
Anakin: "Uh, no loose wire jokes."
Obi-Wan: "Did I say anything?"
Anakin: "He's trying."
Obi-Wan: "I didn't say anything!"

I typed this entirely from memory. As you've noticed, Obi-Wan

has most of the dialogue in that scene.
