Two sneak peaks of the upcoming science fiction films Dredd (that’s the Judge Dredd reboot) and the new Riddick sequel (starring Vin Diesel) were released in the form of new promo photos this week.  It’s something of a treat for fans of sci-fi dystopias featuring brooding and musclebound anti-heros, man-hating prostitutes of the future, and highly unnecessary reboots and sequels.

Dredd was featured in The LA Times, which included a new photo of Lena Heady as Madeline “Ma-Ma” Madrigal, along with an exclusive interview with the actress.

“She’s a prostitute who then kills her pimp and takes over his drug-running business,” says Headey of her role. “And Ma-Ma is a bit of a man-hater.”

The movie takes place among the wild streets of Mega City One, the lone oasis of quasi-civilization on Cursed Earth. Judge Dredd, played by Karl Urban, is the infamously feared elite Street Judge (previously played by Sylvester Stallone in the original film, Judge Dredd), who holds the power to enforce the law and sentence offenders – sometimes even executing them on the spot – if necessary.

“I think of her like an old great white shark who is just waiting for someone bigger and stronger to show up and kill her,” continued the Game of Thrones star. “She’s ready for it. In fact, she can’t wait for it to happen. And yet no one can get the job done. She’s an addict, so she’s dead in that way, but that last knock just hasn’t come. This big, fat, scarred shark moving through the sea and everyone flees and she’s like, ‘Will someone just have the balls to do it? Please?’”

Dredd will be released in 2D and 3D on September 21.

Meanwhile, Riddick star Vin Diesel was happy to share a sexy shirtless set photo from the new movie that’s sure to appeal to female fans, along with this message regarding the latest in the third film his hard-bitten sci-fi series:

“A still from the Riddick set this year… we are in post and I can’t tell you how excited I am to see it manifest. You all were such a part of it becoming a reality… willed it into being, so to speak…”

The star has already let slip that his Riddick will have not one, not two, but three new looks.

Riddick will be released to theaters in 2013 and stars Vin Diesel, Joel William Gonzales, Karl Urban, Katee Sackhoff, Jordi Mollà, Matthew Nable, Bokeem Woodbine, Dave Bautista. The film is directed by David Twohy.
