Jamie Lee Curtis and Lindsay Lohan became lifelong friends when they starred together in 2003's 'Freaky Friday.' Look back on their friendship in photos.

It's been more than two decades since the body-swap comedy that captured the sometimes complicated bond between mothers and daughters became an instant hit. But Freaky Friday fans are just learning that the movie could have ended up very different as Jamie Lee Curtis wasn't actually the first pick to play the mother.

"All they need is each other. That’s the missing piece they weren’t acknowledging the whole time,” Lohan tells EW.
