Just saw this on Jennifer Klein's Facebook page. I always wondered what a "live action" Lion King might be like and this gives some idea. It's fan-made and some of the shots are rather pedestrian, while some are computer assisted but for some scenes they found some pretty good matching live action footage. The first clip has been around a long time (I found it first at http://www.lionking.net/otherstuff.shtml circa 1998), but I'm including it here because it's a great version of "Circle of Life" and because this new fan-made Lion King starts after the opening song ends.
And a "trailer" for a live-action Simba's Pride:
