Actors/musicians who became worse after getting old and fat

Orson Welles was already chubby when he was young, and he still did some kino after becoming obese, like “Chimes at Midnight”.

Brando was number 1 imo. I know many people praise him for “Apocalypse Now” but his performance on that film was basically being extremely lazy. He showed up fat, didn't read the lines and came up with an improvised incoherent rambling monologue, from that on he went downhill. 90s and early 2000s Brando was just a comic relief.

Plenty of actors improve with age (hugh laurie, maggie smith) but no one recovers from getting fat.
