After years of living in London, Lord Greystoke returns to Africa to stop a mining company from exploiting the natives and killing off his adoptive tribe of Apes. He's accompanied by his wife Jane (Margot Robbie) and an American, George Washington Williams (Samuel L Jackson). They quickly slip back to the life in Africa, and we're shown flashbacks of Tarzan's origin, of how his parents died and he was raised by Great Apes. The main villain is the leader of the mining operation, Leon Rom (Christoph Waltz), who will let nothing stop his vision. And Tarzan also has to fight Chief Mbonga (Djimon Hounsou), who wants revenge on Tarzan for killing his son years ago.
Although some things are changed around in the script, this is one of the better film versions of Tarzan. Alexander Skarsgard does a great job as John Clayton/Tarzan, though he's a little too big, and Margot Robbie's Jane is a bit too shrill. However, there's much more right about this movie than wrong and it's worth checking out just for the ape and animal scenes alone. The only better Tarzan adaption I've seen is Filmation's LORD OF THE JUNGLE cartoon from the 70's. Highly recommended.
