300
Over 1,500 visual effects were laid over bluescreens in the epic period action movie 300. Lena Headey found it bizarre to work on a set with so few props. "It's very odd, and emotionally, there's nothing to connect to apart from another actor." Only one scene in the whole film, where horses rode across a plain, was shot outdoors.
Wolf of Wall Street
The visual effects in Martin Scorcese's Oscar-winning hit The Wolf of Wall Street were so discreet that you may not have realized the actors were even on a sound stage. The final shot featured above is almost entirely a digital composite. There's always more than what meets the eye!
