According to Latino Review, who've offered various reliable scoops in the past, especially involving Marvel movies, the studios' untitled flick that'll be released in 2014, along with the Captain America sequel, is the live-action debut of Wakanda's very own T'Challa; AKA the Black Panther. Although this big news was expected to announced at this year's San Diego Comic-Con convention, the site says verbatim:
THE BLACK PANTHER is going to headline his own film! How do I know? Let’s say I got it from FOUR different trusted sources. Last year, it was reported that Marvel hired Mark Bailey to pen the script and I hear the script is fantastic.
For those unfamiliar, via Marvel, T'Challa is heir to the centuries-old ruling dynasty of the African kingdom Wakanda, and ritual leader of its Panther Clan. His mother died in childbirth, earning him the enduring hatred of his adopted elder brother, Hunter, who also resented T'Challa for supplanting him in the royal household. Hunter would become the White Wolf, leader of the Hatut Zeraze (Dogs of War), the Wakandan secret police. T'Challa's senses and physical attributes have been enhanced to superhuman levels by the heart-shaped herb.
There have been Easter eggs alluding to the character's existence in Iron Man 2 and Thor. And considering the big-screen adaptation of T'Challa falls into 'phase two' of Marvel's cinematic universe, it's very well possible he could appear in Marvel's The Avengers inevitable sequel. And while many actors have expressed interest in the role, including Michael Jai White, Djimon Hounsou & Adewale Akinnuoye-Agbaje, who do you think fits?
