She had to be married before her ânextâ birthday. There was never an age stated. Trust me, I know this movie like the back of my hand. Also I have the production book, which quotes in âAladdin - The Making of an Animated Filmâ book from 1992. It reads: âOur original plot line for Aladdin had the Sultan saying, âJasmine, the law says you must be married by your sixteenth birthday.â That was the original story concept and it stayed for quiet a while. Then Jeffery started to worry about what kind of message we would be sending all the fifteen-year-olds in the worldâthat itâs okay to get married before your sixteeth birthday? Of course Aladdin is a fairy tale and presumably happened along time ago, but he thought it would be better to change the line to, âmarried to a prince by your next birthday.â âWe added âa princeâ as well, because Jeffery is usually pretty strong about, âWeâve got to spell out what the situation is.â So we made it very clear that Jasmine has to be married by her next birthdayâwhich ever birthday is itâto a prince.â (Mark Henn, page 41). So she was originally going to be sixteen, but they cut that out due to the message. Thus, Jasmine doesnât have an age.
