Chadwick Boseman's 44th birthday: Mark Ruffalo remembers Black Panther star

Marvel Cinematic Universe star Chadwich Boseman died on August 28 at the age of 42 after a four-year battle with colon cancer. Boseman's Avengers movie co-stars Mark Ruffalo and others remembered him on his 44th birthday and imagined a life where the unfortunate event didn't happen.

Chadwick Boseman was diagnosed with colon cancer almost four years ago. However, the Marshall movie star had not spoken publicly about his diagnosis and chose to hide it from his Avengers movie co-stars. Even Marvel Studios head Kevin Fiege was reportedly unaware of his illness. On Chadwick's 44th birthday, his Marvel co-stars took to their social media handles to talk about the time they all spent together -- a time before his untimely death and before the world witnessed the Coronavirus pandemic.
