They had a costume party for the premiere of Halloween Kills, and star Jamie Lee Curtis figured one good horror story deserves another.
She dressed up as Marion Crane from Psycho, the character her mother Janet Leigh famously portrayed...honoring her mom "in ALL her gory...I meant glory!"
And she even brought along a blood-spattered shower curtain, reminiscent of the famous shower scene in Psycho.
Jamie Lee's dress was blue. We really don't know what color Janet Leigh's was, because it was a black and white movie.
This isn't the first time Jamie Lee has portrayed her mom... check out HER version of the shower scene in Scream Queens in the clip below!
