I have nothing but great memories from that day, when a bunch of wild animals (mostly lions ) took over one of our conference rooms at Disney Animation. I believe at this point the drawing session is over, and most artists have left the building. Ruben Aquino and myself were asked to stick around for some B-roll footage that was to be included into the Making of the Lion King documentary.
What an amazing day...some of us could have died. ;)
