10 Worst CGI Moments In Star Wars

The droid factory sequence in Attack of the Clones certainly has its defenders, though it's also entirely emblematic of the movie's biggest problem: creating set-pieces around emerging, largely untested visual effects technologies.

Though from a design perspective the factory is actually a pretty neat locale, it falls into the basic VFX pitfall of failing to convincingly immerse the actors within it.

We're always acutely aware they're actually performing against a single-colour backdrop, and so when Padme and Anakin are apparently almost squished by giant mechanical stamps, we're not remotely sold on the threat.

But surely the most objectionable part of the entice sequence occurs when C-3PO (Anthony Daniels) takes a clumsy tumble through the factory, ending up with his head removed and swapped out for one belonging to a B1 battle droid.

At this point Attack of the Clones basically becomes an animated film or, if we want to be really harsh, a mid-budget video game cutscene.

It hasn't aged well at all, but those who saw the film in the cinema might recall that it didn't look particularly convincing even then. It's ambitious, for sure, but CGI just wasn't far along enough in 2002 to support Lucas' vision for the scene - or several others.
