One great movie that I discovered by accident in the grocery store check out line in 2004 was The Chonicles of Riddick, starring Vin Diesel. I had no idea what the movie was about, although I could tell it was a sci-fi movie of some sort and I'm not that all into sci-fi unless it's very well done like The Matrix Trilogy.
This became one of my favorite movies. Vin is a great actor, and even though I was only familiar at the time with his work in the action movie Triple X, it looked like "my kind of movie". It was and I've watched it many times since then.
Anyway, soon thereafter I bought the first movie in the franchise, Pitch Black, which filled in some of the back story about The Chronicles of Riddick.
You can read about the character here http://en.wikipedia.org/wiki/Riddick and about the movie here http://en.wikipedia.org/wiki/The_Chronicles_of_Riddick.
And yes, I'm hoping the information at the bottom of the last cite/site is correct, that Vin and producer David Twohy are working on a Riddick sequel due to begin filming soon. Here's the clip from wiki:
In a March 8, 2006, article on Comingsoon.net, it was reported that Vin Diesel claimed that a sequel to The Chronicles of Riddick was in the works. According to him, he had already written a storyline that covered a trilogy which began with the Chronicles of Riddick. Another article on Comingsoon.net, written on March 11, 2005, reports that Vin Diesel states that Chronicles 2 was to deal with The Underverse, while Chronicles 3 was to conclude the series with a return to Furya.
An article dated November 10, 2007, on countingdown.com, further indicates that a sequel may be in works - "We're talking about it". David Twohy indicates however that it "probably won't be a Universal movie and probably will be an independent movie" seeing a much smaller budget.
Two more sequels have been confirmed for production, and David Twohy is now writing the scripts. Diesel told MTV News that in spite of the poor reception, the time between the sequels is only about getting it right, not about trying to find support.
"Everyone knows I love the Riddick character and I’m always working on it,” Diesel asserted. “It just takes five years to make another one because David Twohy and I are so precise about it.”
On March 20, 2009, Vin Diesel commented on a sequel in an interview on Friday Night with Jonathan Ross, stating that David Twohy has nearly finished scripts, and is planning to start production on the third film in early 2010.
On November 30, 2009 Vin Diesel left an update on his Facebook page effectively announcing that pre-production work is underway on the Chronicles of Riddick sequel.
