Just one day after we reported that Oscar winner Lupita Nyong'o is in talks to join Marvel's Black Panther, the cast just keeps getting bigger and bigger. Today we have word that Creed star Michael B. Jordan has signed on to join the cast, which also includes Chadwick Boseman as T'challa, a.k.a. Black Panther. While no details have been released regarding his character, it has been rumored that the actor is playing a villain of some sort.

Fans got their first look at Black Panther in Marvel's current blockbuster Captain America: Civil War, which has already earned a whopping $780 million after just one full week in theaters. The post-credit scene in Captain America: Civil War also gave us our first look at Black Panther's homeland of Wakanda, with a massive facility where The Winter Soldier (Sebastian Stan) is now being held. We don't know for sure if Black Panther will be surfacing in any of the other Marvel Cinematic Universe movies that are coming out before Black Panther hits theaters on February 16, 2018.

As for Michael B. Jordan, the actor is no stranger to the superhero genre. Last year, he portrayed Johnny Storm/The Human Torch in 20th Century Fox's Fantastic Four reboot, which failed to make much of a dent at the box office. Ironically, today's casting news comes just hours after we reported that Fantastic Four producer Simon Kinberg still wants to make Fantastic Four 2, but there are no concrete plans for that sequel as of yet. It isn't known for sure how many major characters have yet to be cast in Black Panther, and no story details have been revealed.

Ryan Coogler is directing Black Panther, and he is also currently re-working the script that was originally written by Joe Robert Cole. Producer Kevin Feige revealed last month that Marvel Studios is aiming to start production on Black Panther in January of 2017, but we don't know for sure where exactly filming will take place. We also don't know if another prominent Wakandan character, Andy Serkis' Ulysses Klaue, who was introduced in Avengers: Age of Ultron, will return in Black Panther, but Kevin Feige has said in the past that we haven't seen the last of Klaue.

This project will mark Michael B. Jordan's third collaboration with Ryan Coogler, who has starred in both of the director's feature films thus far, the 2013 drama Fruitvale Station and last year's blockbuster Creed. The actor is also developing a remake of The Thomas Crown Affair, with Jordan set to star in and produce alongside Captain America: Civil War directors Anthony Russo and Joe Russo. Stay tuned for more casting updates for Black Panther.
