C-3PO: "Why don't we just go into lightspeed?"
R2-D2: <beep>
C-3PO: "We can't?"
R2-D2: <beep>
C-3PO: "How would you know the hyperdrive is deactivated?"
R2-D2: <beep>
C-3PO: "The city's central computer told you?"
R2-D2: <beep>
C-3PO: "R2-D2, you know better than to trust a strange computer!"
To my mind, no information is lost with the removal of "We can't?", since it's obvious they can't, and R2-D2's next line is enough explanation; same goes for "The city's central computer told you?". I'd like if either or both these lines could be excised without affecting the rest of the scene. For the first, it would be sufficient to just remove the line; it wouldn't need any actual removal of footage. The second line would be more difficult.
