Michael Clarke Duncan Voicing Kilowog In 'Green Lantern' [UPDATED]

UPDATE: Weeks later, THR confirms that Michael Clarke Duncan is now in talks to voice Kilowog. Original article follows.

As summer movies go, especially ones that are introducing a major new character to the mainstream, Green Lantern has been very low-key. But as Germain discussed earlier today, that is in part because the effects work on the film has been far more demanding than Warner Bros. expected. What else might be wrapped up in the slow effects schedule for the film? Perhaps the finalization of some of the film's CGI-heavy characters. While principal photography finished months ago, reports say there are still roles to cast. One might be the massive alien Green Lantern Kilowog, for whom Michael Clarke Duncan is reportedly being sought.

Latino Review has the casting tip, and emphasizes that the deal isn't yet final.

But this ties in not only with the report about Green Lantern's slow-gestating effects, but some low-level reports that the voice cast for the film's various aliens is not locked. Those reports are a lot less official, but I've heard that from a few quarters, so it is an aspect of the post-production process that might be a factor. Does that mean the film is in serious trouble? Probably not. Sure, we'd rather know that the CGI characters were animated with actors in mind from day one, but if that isn't the case, it doesn't have to be a mark against the movie.

Here's a quick recap of Kilowog's classic comics backstory:

A towering alien with a brutish and porcine appearance, Kilowog is renowned throughout the Green Lantern Corps as the primary trainer of the Corps' newest recruits. The Guardians of the Universe recruited Kilowog, a gifted genetic scientist, from the planet Bolovax Vik, located in Space Sector 674. Kilowog was trained by Lantern Ermey, who would often use the word "Poozer", which meant "useless rookies" (A word Kilowog would later adopt, albeit in a friendlier way). In the middle of a particularly arduous training session, Ermey had Kilowog and his fellow rookies help stop an attack on a group of Lanterns, one of whom was the future renegade Sinestro. Ermey, fatally wounded in battle, commended Kilowog on his abilities, telling him that he had the makings of a great leader.[1] In addition to serving with distinction as the Green Lantern of that sector, Kilowog also began to spend extensive periods of time on the Green Lantern Corps' home planet of Oa instructing new recruits on how to handle and best utilize their power rings. In this capacity, Kilowog acted as the first trainer to a young Hal Jordan, the ring-recruited successor to the slain Abin Sur of Ungara, the Green Lantern of Space Sector 2814. Kilowog and his new recruit helped the Guardians confront Abin Sur's murderer, the hive mind interstellar malefactor known as Legion.
