Seems Fire & Ice will be brought to the big screen:
Robert Rodriguez hit attendees of his Comic-Con panel with the announcement that he's teamed with the estate of fantasy artist Frank Frazetta for a live-action take on his Fire and Ice. The feature will be based on Frazetta's work and the previous 1983 animated version of the film.
Also, two sequels for Machete and one long awaited sequel for Sin City will also be happening. Movieweb writes:
"If Sin City 2 happens, it'll happen this year. I'd also love to do that in 3D - an idea that would translate really well to that format."
Robert Rodriguez also indicated that Sin City 2 will incorporate the graphic novel volume A Dame to Kill For, and two brand new stories written by Frank Miller, one of which is entitled The Long, Bad Night.
Machete is actually getting two sequels, according to Robert Rodriguez, who thanked the fans at his Hall H appearance for supporting the movie. Both sequels have been given the green light by Fox Searchlight, with the first sequel entitled Machete Kills.
"You guys were great about supporting Machete. The second one we're going right into now, Machete Kills."
The director also said that the other sequel, Machete Kills Again, will be a, "space opera, a machete-shaped lightsaber. Machete kills in space."
