When I first saw the movie, I did not guess the ending, hana.
but when I watch the movie again in 4K HD, I notice it was Micheal Cane in the blond wig at the beginning, hana.

Yeah, I figured he was the tranny well be fore the big reveal.
The strong points of the film are the visuals and cinematography which is why this got a Criterion release. Also, tits are good.

Good for 1980 but not today lol. Yeah because the thrillers now are so epic right? Dumb kids

I figured it out seeing the picture of the killer on the back of the soundtrack album! It was bloody obvious who it was wearing sunglasses and a blonde wig!
Was it a millionaire who said "Imagine no possessions"?

Um I knew he was the trans person. That was not a twist if you knew the doctor was the killer.

Moron the twist wasn't that he was the killer, the twist was that he and "Bobbie" were one and the same. So if you tell me that when Elliott was talking to Dr. Levy, you knew at that point that Levy was going "Wow here I am talking to the crazy Dr. that is trying to block his own sex change operation!", I know you're lying.

I figured it out the moment she got killed, after that I stopped watching. It was a bad move to make the killer so obvious.

Sisters is good, too. The main actress in that, Jennifer Salt, was such a babe as Angie Dickinson was in this one.
I always liked this movie and like a previous poster, was hooked on the Hitchcock elements of the film. I didn't pick the twist though when I first saw it and as another poster said, I was busy going over all the things she would've been thinking of in the scenes prior to the elevator.
Mogwai come much responsibility.

I've always liked this movie, it's one of my favorites, I'm a big fan of De Palma's movies in general
Y'know, I could eat a peach for hours

Very good to hear that the new generation is appreciating this classic!

The only reason I worked it out was because of the 'Hitchcock' technique used.
I studied Psycho as a case study in school, and as soon as I saw
the killing of the supposed lead character in the first reel and the story taking a different direction as a result technique, I kind of saw where it was going.
Otherwise, it was very well done, a mix of giallo, Hitchcock and DePalma's personal touch.

i just watched it with 10 friends all guys, 20s and 30s only one figured it out and they loved it of course it's a group of people that like horror and thrillers so maybe they can appreciate the build up and style more than others
what's so great about that elevator scene plus the cat and mouse buildup up to it in the art gallery is we get the idea of what's going on in her mind she's overwhelmed before the killer even approaches
she's concerned about her panties, her ring, she just cheated on her husband with a guy with VD her head is spinning already then suddenly a strange looking woman with a knife appears in front of her
so great

I had never seen or heard of this movie. I loved it until I saw the killer, very disappointing.

I don't get why people say they figured out the twist ending. There wasn't an element of suspecting the ending due to the ads and reviews before watching it?

Although the movie is very flawed, not for the reasons you cite.
For one thing, some people freeze up when approached by razor-weilding psychos I know I do.
Non-sequiturs are delicious.

That was a dream sequence.

That was a dream sequence
Anyway I agree with OP. It was obvious who the killer was.

I agree with you.
One of the ridiculous parts was the psycho in the hospital bed and not restrained at all. Maybe this movie was meant to be more of a comedy/silly thriller.
