Different casting
Before Lindsay Lohan became Anna Coleman, Disney considered Michelle Trachtenberg for the role.
However, Trachtenberg had to turn the project down due to her contract for Buffy the Vampire Slayer, in which she played Dawn Summers.
Meanwhile, Jodie Foster - who portrayed Anna Coleman’s stand-in Annabel Andrews in the original 1976 Freaky Friday movie - was approached to play the mother Tess Coleman in the new film, though ultimately rejected the offer as she thought her casting might be a distraction.
Annette Bening had then been cast as Tess, though she parted ways with the project just six days before filming began - allowing Jamie Lee Curtis to swoop in and take the part.
