10 Stunning Movies With One Awful CGI Moment

Tron: Legacy was a major visual effects milestone in many key areas, and remains one of the most visually intoxicating blockbusters of the last decade.

But there's one element of the film that even VFX necromancers Digital Domain couldn't convincingly pull off - creating a fully CGI rendition of a younger Jeff Bridges for the character of Clu, the Grid's corrupt ruler.

The effects team created Clu using reference material from the Bridges-starring 1984 film Against All Odds, and if you know anything about visual effects at all, you'll know that recreating a human's face from scratch is one of the toughest tasks you can ask artists to do.

But it goes without saying that Clu never quite convinces as a lifelike younger Flynn, with his plastic skin texture and robotic facial animations remaining firmly stuck in the uncanny valley.

In another movie this might seem quite impressive, but given that Legacy is a feast for the eyes otherwise, it feels like a step or two below the rest of the production.

And though like The Matrix Reloaded you can argue that Clu is supposed to look a bit uncanny, being a digital facsimile of Flynn and all, that clearly wasn't the look they were aiming for.
