'You will always be our king': Marvel honours Chadwick Boseman with moving Black Panther tribute

Marvel has paid tribute to Black Panther star Chadwick Boseman in an emotional behind-the-scenes look at the iconic role he played while secretly battling the colon cancer, which claimed his life earlier this week. 

The video features Boseman's Black Panther co-stars Lupita Nyong'o, Michael B Jordan and Angela Bassett, all of whom rave about the actor's talent in playing King T'Challa in footage filmed before his death. 

The 43-year-old fought cancer for four years, mostly in private, with a statement from his family revealing he filmed his movies in between and during bouts of chemotherapy and several surgeries. 

Boseman's family said his role in the history-making superhero movie Black Panther was the "honour of his career". 

The film's director Ryan Coogler and Marvel Studios president Kevin Feige also gave interviews in the tribute clip, with Coogler hailing Boseman as "incredibly gifted... a story-teller in his own right". 

Marvel universe stalwarts Robert Downey Jr, Scarlett Johansson and Chris Evans all had kind words for Boseman too, with Evans dubbing him a "powerhouse" in every film he appeared in. 

Collider reports that all the interviews about Boseman were given well before his death, and given reports of his secrecy around his health issues, many of his co-stars and colleagues were unlikely to have been aware of his deteriorating condition at the time. Da 5 Bloods director Spike Lee revealed he had "no idea" Boseman was going through treatment during the film's gruelling shoot in the jungles of Thailand.
