The 49-year-old star played Hela in Thor Ragnarok, the goddess of death and sister of Hemsworth’s Asgardian prince.
However as usual for Marvel villains, she was defeated at the film’s end when Asgard was destroyed.
Yet as comic book characters are prone to do, could she be making a big comeback?
Blanchett is currently promoting her new film, The House with a Clock in Its Walls and she recently asked about returning as Hela.
Speaking with FANDOM, her co-star Jack Black said: “[We] never actually saw her die. You just saw her go down in a giant ball of flame.”
Blanchett responded that Hela “looks pretty dead” but is open to a resurrection of sorts.
She added: “There’s always a way back, but I’m sure there’s always a way forward.
“Who know? Sure. I never say no to anything.”
Asked if she would like to team up with Thanos, who falls in love with the goddess of Death in the comics, Blanchett certainly didn’t say no.
She said: “That would be good.”
However she teased it would “not [be] nice” for the Avengers.
Of course one possibility is that Blanchett is playing it coy and Hela will return in Avengers 4.
After all it’s unlikely that Thanos will appear in future MCU movies, as Josh Brolin has teased Avengers 4 is his last one in the franchise.
There’s also the fact there’s been rumours of dead characters like Crossbones, Peggy Carter and Howard Stark reappearing in a film that’s rumoured to be heavy on time travel.
It would certainly be a great way to celebrate 10 years of the MCU with trips back to past movies.
Avengers 4 is released in UK cinemas on April 26, 2019.
