The actress -- famous for playing Wanda Maximoff/Scarlet Witch throughout the 'Avengers' movies -- got candid yet again this weekend in a sit-down interview with Meghann Fahy, as part of Variety's 'Actors on Actors' series. One quote of hers is getting a double-take online.

Fahy asks Olsen if she stays up at night missing Wanda -- or playing her, presumably -- and EO's reaction is telling. She says she doesn't ... but you gotta watch *how* she says it.

There's a little bit of sass and saltiness in her response, and you can tell she truly means it. As she goes on to explain, she's played that character for the better part of 10 years, and she's more than ready to put Wanda's stories on the bookshelf ... at least for now.

Olsen adds that she's proud of the work she did with Kevin Feige and co. ... and feels content with letting those projects speak for themselves -- including "WandaVision," which was a huge Disney+ hit that focused solely on her role, with a full-fledged backstory.

So, her take here seems to be two-fold -- yes, she's over it and has no desire to link up again anytime soon ... but also, she's grateful for the opportunity to have been a superhero.

BTW, her response here about missing Wanda is very much in line with other comments she's made of late about Marvel. She's been on the record over the past year or so -- via several outlets -- saying that she wishes she would've only given the Mouse House one year of her services as opposed to several ... as there were times she was frustrated.

She's said she felt, at times, like she missed out on other interesting opportunities -- remember, she comes from an indie film background -- that she might've liked to have pursued. But, because she was under contract with Marvel, she had to pass on 'em.
