It's after Tuesday, so here's the other one I promised:
Legolas shooting Gríma on the top of Orthanc!
*Rant on why I don't like what PJ did...* and besides that, I've calculated it: it is physically impossible. In order to gain enough initial velocity to get to the top of Orthanc, at the moment of being released the arrow would have had to withstand an acceleration of 22,227.4 m/sq. s. Not even Lego's spiffy little elf arrow could do that.
