David Twohy has revealed the logo for his upcoming sci-fi action film Riddick. The director also said that it is "crunch time" as he works relentlessly to wrap up the visual and audio effects in the film.

Here he is talking about the time spent on the film making process.

"Been pulling 14-hour days trying to finish Riddick. My typical day starts at 9am with intensive visual effects meetings, sweating out the details of our 900 VFX shots. Then I jet across town to the mix stage, Soundelux, where I supervise the sound, balancing out the often-competing elements of music, sound fx, sound design, and dialog. At night I hit the lab, Technicolor in Hollywood, staying until midnight to do "DI work" - color-correction of the movie. This is where David Eggby and I have one last chance to get the images right, dropping in grads and power windows to finesse what we shot on set. It's a great tool, the Digital Intermediate. Kind of like Photoshop for movies. Gotta love it. Gotta love the challenge of bringing it all home."
