Wheelchair Calamari Guy as Sex God (plot spoiler)

What's the name of the movie with an old character actor (he's definitely European, likely fat, and maybe bald) who plays a wheelchair-bound billionaire-type and pleases women with his master tongue because he has no dick. I want to say it's an espionage film set in Europe. ETA: In retrospect, maybe he's not in a wheelchair because it would make the twist more obvious.

After a lot of prying, ChatGPT came up with The Debt, but I don't remember ever watching that. I also think it might be hallucinating because it had some obviously wrong answers before even that (Kingsman, Red Sparrow). It also had The International (Clive Owen), but I'm pretty sure that's also wrong.
