It's a different pronunciation, not just his accent. And it's hardly slightly is it? There's a limited number of ways a word can be read, and this way was as different as possible.Hey, as a man once said; "New mouth, new rules!"
Exactly. After all the Seventh Doctor developed a Scottish accent, why can't the Eleventh pronounce some place names slightly differently?
Oh yes, that'll be it. I bet if you pick up the script it noted for Smith to pronounce it differently because the writer decided the Third Doctor had been saying it wrong.Has it not occurred to anyone that, maybe, it was Three who was pronouncing it wrong to begin with? (Another thing he got totally wrong about that planet.)
Why was this episode called Hide?
