He explains that they're on Earth, in an actual gravel quarry. <img src="/images/icons/tongue.gif" /> (Unfortunately, one that's just finished setting up to do some blasting....)<br /><br />Then there was the charity spoof "The Curse of Fatal Death". "All those endless gravel quarries...."<br /><br />The upcoming "Impossible Planet" is filmed on a sound stage, with the alien world realized through sets and CGI. Visually, I think it works quite well. Another non-Earth setting this season was in "New Earth". Obviously the planet resembled Earth fairly well, superficially, but it definitely wasn't Earth. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
