Dead Ringers and the creepiest twins in cinema?

Okay, so I finally watched "Dead Ringers" (1988) and wow, did it leave me feeling… unsettled. I knew it was Cronenberg and all that, so I expected some body horror goodness (or badness, depending on your stomach!), but it was Jeremy Irons, playing identical twin gyns Elliot and Beverly Mantle, that really got to me. The way he navigated those two roles, the subtle shifts in posture, expression, even just the vibe he gave off as each brother… it was masterful. You could tell them apart even without the dialogue. Elliot, the confident, womanizing one, felt almost predatory, especially in those early scenes with his patients. And then Beverly, so shy and insecure, just wanting connection but totally unable to handle it when he gets it... That sequence where he's falling apart because of Claire Niveau (played by a perfectly cast Geneviève Bujold!), spiraling into drug addiction... heartbreaking and disturbing all at once. The scene where he's trying to get Claire to trust him and then he just descends into a giggling madman is probably the most unsettling and revealing of how unhinged and insecure Beverly is. I honestly wasn't expecting to get so emotionally invested. Like, the creepy gynecological instruments and the 'mutant woman' obsession was definitely there, and yes I did squirm, but it was Irons' performance(s!) that really elevated it for me. I think I might have to watch it again just to appreciate all that work. Anyone else find those twins ridiculously compelling, even though they were complete messes? My only real gripe is that I wish the final act had been a little less… rushed? The ending felt a bit abrupt after such slow burn of a descent into madness. But honestly, that's a minor point. This movie sticks with you, and Irons deserves all the praise. Seriously, how did he do that?!
