James Cameron's Avatar was a pioneer in film technology, ushering in the 3D age. Don't expect the long-awaited sequels to do the same for HFR though.

Stuck in development hell as it bounced around Hollywood for over 20 years, Gemini Man is finally hitting the big screen boasting some eye-watering technological leaps. But was all this filmmaking wizardry worth the wait?

The script for Gemini Man has been bouncing around Hollywood for 20 years before director Ang Lee and star Will Smith tackled this movie of a hitman having to face a younger cloned version of himself. And according to the first reactions to it, it was worth the wait.

Following on from yesterday's behind-the-scenes featurette taking a look at the amazing VFX of Gemini Man, we have some new production info and a trailer for the Will Smith vs Will Smith sc-fi action thriller.

Visual effects are now allowing films to turn back the hands of time on their actors.

Gemini Man is the upcoming sci-fi action thriller from director Ang Lee and starring Will Smith. He portrays Henry Brogan, an elite assassin, who is suddenly targeted and pursued by a mysterious young operative that seemingly can predict his every move.

A film that has been in on-off development for over 20 years, seems to finally be gaining traction with Ang Lee and Will Smith on-board for the project.

A film that should be a great piece of art that despite its cast sadly ends up little more than the remains of a failed amateurish experiment
