Best known for his regal role as King T’Challa in "Black Panther," his fans, co-stars, and many others flooded social media to remember the phenomenal actor on what would have been his birthday.

Lupita Nyong’o took to Twitter and shortly wrote, “Deeply loved, sorely missed,” while Viola Davis tweeted, “Happy Birthday in Heaven, Chadwick! You are still so alive to me!! I love you with yellow heart emojis.

One fan thanked Ruffalo for sharing in what is a beautiful moment to them. The fan added that Boseman's legacy would continue to live forever and referred to the beloved actor as a true King.

Boseman’s co-stars and fans are not the only ones honoring his memory. Disney also marked a tribute to him into the opening of his landmark film with them. Boseman was certainly a true icon.

According to TMZ, on Sunday morning, "Black Panther" on the Disney+ channel featured a new opening credits sequence, which now shows Boseman instead of the Marvel Logo. Marvel then posted the recent opening credits on social media.

Marvel captioned the post saying Long live the King, #WakandaForever. Boseman's images and footage of him are also embedded into the Marvel logo artwork, from the film, and in real life.

Many have paid their respects to the fallen superhero in the form of tattoos, art pieces, statues, murals, and re-worked comic books to honor his memory. The legend will surely always be in his fans’ hearts and all those who adored him.
