Mark Ruffalo

He play the Incredible Hulk in the Marvel Cinematic Universe but Ruffalo has been left green with sickness due to his Lyme disease diagnosis.

He took to Twitter - now known as X - in 2017 to reveal he was a Lyme disease sufferer and urged his followers to watch documentary The Quiet Epidemic about the illness.

Ruffalo said: "From personal experience, Lyme disease can be brutal, persistent and misdiagnosed. The healthcare industry is way behind on this disease."
